This commit is similar to 379805051d ("Documentation: render revisions
correctly under Asciidoctor", 2018-05-06) and is a no-op with AsciiDoc.
When creating a literal block from an indented block without any sort of
delimiters, Asciidoctor strips off all leading whitespace, resulting in
a misrendered ASCII drawing. Use an explicit literal block to indicate
to Asciidoctor that we want to keep the leading whitespace. Drop the
common indentation for all lines to make this a no-op with AsciiDoc.

user-manual.txt is the only file we process using the "book" doctype.
When we use AsciiDoc, user-manual.conf ensures that the linkgit macro
expands into something like
<ulink url="git-foo.html">git-foo(1)</ulink>
in user-manual.xml, which we then process into a clickable link, both in
user-manual.html and user-manual.pdf. With Asciidoctor,
user-manual.conf is ignored (this is expected) and our
Asciidoctor-specific implementation of linkgit kicks in:
<citerefentry>
<refentrytitle>git-foo</refentrytitle><manvolnum>1</manvolnum>
</citerefentry>
This eventually renders as "git-foo(1)", which is not bad, but it
doesn't turn into a link.
Teach our Asciidoctor-specific implementation of the linkgit macro that
if the doctype is "book", we should emit <ulink .../> just like we do
with AsciiDoc. While we're doing this, future-proof by supporting a
"prefix". The implementation in user-manual.conf doesn't support this,
and we don't need this for now because user-manual.txt is the only file
we process this way (and it's immediately in Documentation/).

When AsciiDoc processes user-manual.txt, it generates a book containing
chapters containing sections. So for example, we have chapter 6,
"Advanced branch management", which contains four relatively short
sections, 6.1-6.4. Asciidoctor generates a book containing *parts*
containing *chapters* instead. So part 6, "Advanced branch management"
contains four short chapters, 1-4. This looks a bit odd.
To make AsciiDoc (8.6.10) and Asciidoctor (1.5.5) handle these the same,
change from indicating chapters like so:
[[foobar]]
Foobar
======
to doing it like so:
[[foobar]]
== Foobar
Same thing for sections (line of dashes to ===), subsections (line of
tildes to ====) and subsubsections (line of carets to =====). Mark the
appendices with "[appendix]", which both AsciiDoc and Asciidoctor
understand. This means we need to drop the "Appendix X: " from their
titles, or those "Appendix X: " would be included literally in the name
of the appendix.
This commit is a no-op for AsciiDoc: The generated user-manual.xml is
identical before and after this patch. Asciidoctor now creates the same
chapter-section-subsection structure as AsciiDoc.
Changing the book title at the start of the document to similarly use
"=" instead of a line of equal signs makes no difference with any of the
engines, but let's do that change anyway for consistency.

Users expect files in a nested git repository to be left alone unless
sufficiently forced (with two -f's). Unfortunately, in certain
circumstances, git would delete both tracked (and possibly dirty) files
and untracked files within a nested repository. To explain how this
happens, let's contrast a couple cases. First, take the following
example setup (which assumes we are already within a git repo):
git init nested
cd nested
>tracked
git add tracked
git commit -m init
>untracked
cd ..
In this setup, everything works as expected; running 'git clean -fd'
will result in fill_directory() returning the following paths:
nested/
nested/tracked
nested/untracked
and then correct_untracked_entries() would notice this can be compressed
to
nested/
and then since "nested/" is a directory, we would call
remove_dirs("nested/", ...), which would
check is_nonbare_repository_dir() and then decide to skip it.
However, if someone also creates an ignored file:
>nested/ignored
then running 'git clean -fd' would result in fill_directory() returning
the same paths:
nested/
nested/tracked
nested/untracked
but correct_untracked_entries() will notice that we had ignored entries
under nested/ and thus simplify this list to
nested/tracked
nested/untracked
Since these are not directories, we do not call remove_dirs() which was
the only place that had the is_nonbare_repository_dir() safety check --
resulting in us deleting both the untracked file and the tracked (and
possibly dirty) file.
One possible fix for this issue would be walking the parent directories
of each path and checking if they represent nonbare repositories, but
that would be wasteful. Even if we added caching of some sort, it's
still a waste because we should have been able to check that "nested/"
represented a nonbare repository before even descending into it in the
first place. Add a DIR_SKIP_NESTED_GIT flag to dir_struct.flags and use
it to prevent fill_directory() and friends from descending into nested
git repos.
With this change, we also modify two regression tests added in commit
91479b9c72f1 ("t7300: add tests to document behavior of clean and nested
git", 2015-06-15). That commit, nor its series, nor the six previous
iterations of that series on the mailing list discussed why those tests
coded the expectation they did. In fact, it appears their purpose was
simply to test _existing_ behavior to make sure that the performance
changes didn't change the behavior. However, these two tests directly
contradicted the manpage's claims that two -f's were required to delete
files/directories under a nested git repository. While one could argue
that the user gave an explicit path which matched files/directories that
were within a nested repository, there's a slippery slope that becomes
very difficult for users to understand once you go down that route (e.g.
what if they specified "git clean -f -d '*.c'"?) It would also be hard
to explain what the exact behavior was; avoid such problems by making it
really simple.
Also, clean up some grammar errors describing this functionality in the
git-clean manpage.
Finally, there are still a couple bugs with -ffd not cleaning out enough
(e.g. missing the nested .git) and with -ffdX possibly cleaning out the
wrong files (paying attention to outer .gitignore instead of inner).
This patch does not address these cases at all (and does not change the
behavior relative to those flags), it only fixes the handling when given
a single -f. See
https://public-inbox.org/git/20190905212043.GC32087@szeder.dev/ for more
discussion of the -ffd[X?] bugs.

The -d flag pre-dated git-clean's ability to have paths specified. As
such, the default for git-clean was to only remove untracked files in
the current directory, and -d existed to allow it to recurse into
subdirectories.
The interaction of paths and the -d option appears to not have been
carefully considered, as evidenced by numerous bugs and a dearth of
tests covering such pairings in the testsuite. The definition turns out
to be important, so let's look at some of the various ways one could
interpret the -d option:
A) Without -d, only look in subdirectories which contain tracked
files under them; with -d, also look in subdirectories which
are untracked for files to clean.
B) Without specified paths from the user for us to delete, we need to
have some kind of default, so...without -d, only look in
subdirectories which contain tracked files under them; with -d,
also look in subdirectories which are untracked for files to clean.
The important distinction here is that choice B says that the presence
or absence of '-d' is irrelevant if paths are specified. The logic
behind option B is that if a user explicitly asked us to clean a
specified pathspec, then we should clean anything that matches that
pathspec. Some examples may clarify. Should
git clean -f untracked_dir/file
remove untracked_dir/file or not? It seems crazy not to, but a strict
reading of option A says it shouldn't be removed. How about
git clean -f untracked_dir/file1 tracked_dir/file2
or
git clean -f untracked_dir_1/file1 untracked_dir_2/file2
? Should it remove either or both of these files? Should it require
multiple runs to remove both the files listed? (If this sounds like a
crazy question to even ask, see the commit message of "t7300: Add some
testcases showing failure to clean specified pathspecs" added earlier in
this patch series.) What if -ffd were used instead of -f -- should that
allow these to be removed? Should it take multiple invocations with
-ffd? What if a glob (such as '*tracked*') were used instead of
spelling out the directory names? What if the filenames involved globs,
such as
git clean -f '*.o'
or
git clean -f '*/*.o'
?
The current documentation actually suggests a definition that is
slightly different than choice A, and the implementation prior to this
series provided something radically different than either choices A or
B. (The implementation, though, was clearly just buggy). There may be
other choices as well. However, for almost any given choice of
definition for -d that I can think of, some of the examples above will
appear buggy to the user. The only case that doesn't have negative
surprises is choice B: treat a user-specified path as a request to clean
all untracked files which match that path specification, including
recursing into any untracked directories.
Change the documentation and basic implementation to use this
definition.
There were two regression tests that indirectly depended on the current
implementation, but neither was about subdirectory handling. These two
tests were introduced in commit 5b7570cfb41c ("git-clean: add tests for
relative path", 2008-03-07) which was solely created to add coverage for
the changes in commit fb328947c8e ("git-clean: correct printing relative
path", 2008-03-07). Both tests specified a directory that happened to
have an untracked subdirectory, but both were only checking that the
resulting printout of a file that was removed was shown with a relative
path. Update these tests appropriately.

diff, log doc: say "patch text" instead of "patches"
A poster on Stackoverflow was confused that the documentation of git-log
promised to generate "patches" or "patch files" with -p, but there were
none to be found. Rewrite the corresponding paragraph to talk about
"patch text" to avoid the confusion.
Shorten the language to say "X does Y" in place of "X does not Z, but Y".
Cross-reference the referred-to commands like the rest of the file does.
Enumerate git-show because it includes the description as well.
Mention porcelain commands before plumbing commands because I guess that
the paragraph is read more frequently in their context.

After the previous commit, AsciiDoc and Asciidoctor render the manpage
headers identically, so we no longer need the "cut the header" part of
our `--cut-header-footer` option. We do still need the "cut the footer"
part, though. The previous commits improved the rendering of the footer
in Asciidoctor by quite a bit, but the two programs still disagree on
how to format the date in the footer: 01/01/1970 vs 1970-01-01.
We could keep using `--cut-header-footer`, but it would be nice if we
had a slightly smaller hammer `--cut-footer` that would be less likely
to hide regressions. Rather than simply adding such an option, let's
also drop `--cut-header-footer`, i.e., rework it to lose the "header"
part of its name and functionality.
`--cut-header-footer` is just a developer tool and it probably has no
more than a handful of users, so we can afford to be aggressive.

As can be seen from the previous commit, there are three attributes that
we provide to AsciiDoc through asciidoc.conf. Asciidoctor ignores that
file. After that patch, newer versions of Asciidoctor pick up the
`manmanual` and `mansource` attributes as we invoke `asciidoctor`, but
they don't pick up `manversion`. ([1] says: "Not used by Asciidoctor.")
Older versions (<1.5.7) don't handle these attributes at all. As a
result, we are missing one or three `<refmiscinfo/>` tags in each
xml-file produced when we build with Asciidoctor.
Because of this, xmlto doesn't include the Git version number in the
rendered manpages. And in particular, with versions <1.5.7, the manpage
footers instead contain the fairly ugly "[FIXME: source]".
That Asciidoctor ignores asciidoc.conf is nothing new. This is why we
implement the `linkgit:` macro in asciidoc.conf *and* in
asciidoctor-extensions.rb. Follow suit and provide these tags in
asciidoctor-extensions.rb, using a "postprocessor" extension where we
just search and replace in the XML, treated as text.
We may consider a few alternatives:
* Inject these lines into the xml-files from the *Makefile*, e.g.,
using `sed`. That would reduce repetition, but it feels wrong to
impose another step and another risk on the AsciiDoc-processing only
to benefit the Asciidoctor-one.
* I tried providing a "docinfo processor" to inject these tags, but
could not figure out how to "merge" the two <refmeta/> sections that
resulted. To avoid xmlto barfing on the result, I needed to use
`xmlto --skip-validation ...`, which seems unfortunate.
Let's instead inject the missing tags using a postprocessor. We'll make
it fairly obvious that we aim to inject the exact same three lines of
`<refmiscinfo/>` that asciidoc.conf provides. We inject them in
*post*-processing so we need to do the variable expansion ourselves. We
do introduce the bug that asciidoc.conf already has in that we won't do
any escaping, e.g., of funky versions like "some v <2.25, >2.20".
The postprocessor we add here works on the XML as raw text and doesn't
really use the full potential of XML to do a more structured injection.
This is actually precisely what the Asciidoctor User Manual does in its
postprocessor example [2]. I looked into two other approaches:
1. The nokogiri library is apparently the "modern" way of doing XML
in ruby. I got it working fairly easily:
require 'nokogiri'
doc = Nokogiri::XML(output)
doc.search("refmeta").each { |n| n.add_child(new_tags) }
output = doc.to_xml
However, this adds another dependency (e.g., the "ruby-nokogiri"
package on Ubuntu). Using Asciidoctor is not our default, but it
will probably need to become so soon. Let's avoid adding a
dependency just so that we can say "search...add_child" rather than
"sub(regex...)".
2. The older REXML is apparently always(?) bundled with ruby, but I
couldn't even parse the original document:
require 'rexml/document'
doc = REXML::Document.new(output)
...
The error was "no implicit conversion of nil into String" and I
stopped there.
I don't think it's unlikely that doing a plain old search-and-replace
will work just as fine or better compared to parsing XML and worrying
about libraries and library versions.

Rather than hardcoding "Git Manual" and "Git" as the manual and source
in asciidoc.conf, provide them as attributes `manmanual` and
`mansource`. Rename the `git_version` attribute to `manversion`.
These new attribute names are not arbitrary, see, e.g., [1].
For AsciiDoc (8.6.10) and Asciidoctor <1.5.7, this is a no-op. Starting
with Asciidoctor 1.5.7, `manmanual` and `mansource` actually end up in
the xml-files and eventually in the rendered manpages. In particular,
the manpage headers now render just as with AsciiDoc.
No versions of Asciidoctor pick up the `manversion` [2], and older
versions don't pick up any of these attributes. -- We'll fix that with a
bit of a hack in the next commit.

In b57e8119e6 (submodule: teach set-branch subcommand, 2019-02-08), the
`set-branch` subcommand was added for submodules. When the documentation
was written, the syntax for a "index term" in AsciiDoc was
accidentally used. This caused the documentation to be rendered as
set-branch -d|--default)|(-b|--branch <branch> [--] <path>
instead of
set-branch ((-d|--default)|(-b|--branch <branch>)) [--] <path>
In addition to this, the original documentation was possibly confusing
as it made it seem as if the `-b` option didn't accept a `<branch>`
argument.
Break `--default` and `--branch` into their own separate invocations to
make it obvious that these options are mutually exclusive. Also, this
removes the surrounding parentheses so that the "index term" syntax is
not triggered.

Our documentation toolchain has traditionally been built around DocBook
4.5. This version of DocBook is the last DTD-based version of DocBook.
In 2009, DocBook 5 was introduced using namespaces and its syntax is
expressed in RELAX NG, which is more expressive and allows a wider
variety of syntax forms.
Asciidoctor, one of the alternatives for building our documentation,
moved support for DocBook 4.5 out of core in its recent 2.0 release and
now only supports DocBook 5 in the main release. The DocBoook 4.5
converter is still available as a separate component, but this is not
available in most distro packages. This would not be a problem but for
the fact that we use xmlto, which is still stuck in the DocBook 4.5 era.
xmlto performs DTD validation as part of the build process. This is not
problematic for DocBook 4.5, which has a valid DTD, but it clearly
cannot work for DocBook 5, since no DTD can adequately express its full
syntax. In addition, even if xmlto did support RELAX NG validation,
that wouldn't be sufficient because it uses the libxml2-based xmllint to
do so, which has known problems with validating interleaves in RELAX NG.
Fortunately, there's an easy way forward: ask Asciidoctor to use its
DocBook 5 backend and tell xmlto to skip validation. Asciidoctor has
supported DocBook 5 since v0.1.4 in 2013 and xmlto has supported
skipping validation for probably longer than that.
We also need to teach xmlto how to use the namespaced DocBook XSLT
stylesheets instead of the non-namespaced ones it usually uses.
Normally these stylesheets are interchangeable, but the non-namespaced
ones have a bug that causes them not to strip whitespace automatically
from certain elements when namespaces are in use. This results in
additional whitespace at the beginning of list elements, which is
jarring and unsightly.
We can do this by passing a custom stylesheet with the -x option that
simply imports the namespaced stylesheets via a URL. Any system with
support for XML catalogs will automatically look this URL up and
reference a local copy instead without us having to know where this
local copy is located. We know that anyone using xmlto will already
have catalogs set up properly since the DocBook 4.5 DTD used during
validation is also looked up via catalogs. All major Linux
distributions distribute the necessary stylesheets and have built-in
catalog support, and Homebrew does as well, albeit with a requirement to
set an environment variable to enable catalog support.
On the off chance that someone lacks support for catalogs, it is
possible for xmlto (via xmllint) to download the stylesheets from the
URLs in question, although this will likely perform poorly enough to
attract attention. People still have the option of using the prebuilt
documentation that we ship, so happily this should not be an impediment.
Finally, we need to filter out some messages from other stylesheets that
occur when invoking dblatex in the CI job. This tool strips namespaces
much like the unnamespaced DocBook stylesheets and prints similar
messages. If we permit these messages to be printed to standard error,
our documentation CI job will fail because we check standard error for
unexpected output. Due to dblatex's reliance on Python 2, we may need
to revisit its use in the future, in which case this problem may go
away, but this can be delayed until a future patch.
The final message we filter is due to libxslt on modern Debian and
Ubuntu. The patch which they use to implement reproducible ID
generation also prints messages about the ID generation. While this
doesn't affect our current CI images since they use Ubuntu 16.04 which
lacks this patch, if we upgrade to Ubuntu 18.04 or a modern Debian,
these messages will appear and, like the above messages, cause a CI
failure.

works fine with AsciiDoc (8.6.10), and almost fine with Asciidoctor
(1.5.5), which renders the third of these literally ("+$projname+"). The
reason seems to be that Asciidoctor trips on the lone plus a bit
earlier, even though it is escaped.
Switch +$projname+ to `$projname`, and change the next, similar instance
too (+$projname/+), because otherwise, we'd trip on /that one/ instead.
If we would stop there, we would now start falling over on the escaped
plus ('\+') mentioned earlier, rendering /it/ literally. So change that
too...
In other words, unescape the lone '+' and change all the pluses that
follow it to backticks.
AsciiDoc renders this paragraph identically before and after this
commit, and Asciidoctor now renders this the same as AsciiDoc.
I did try to switch the whole paragraph to using backticks rather than
pluses. That worked great with Asciidoctor, but confused AsciiDoc...
Let's go with this rather surgical change instead.

The example output of `git merge-index` has been enriched by a second
"column" of helpful comments. When Asciidoctor renders this, the cells
in that second column aren't aligned.
Fix this by marking the example shell session as a code listing by
wrapping it in "----". Also drop some of the horizontal space between
the two columns so that we fit into 80 columns. This changes the
rendering with both AsciiDoc and Asciidoctor. They now render this
identically, nicely aligned, and within 80 columns.

The indented lines in the example shell script listing are indented
differently by AsciiDoc and Asciidoctor.
Fix this by marking the example shell script as a code listing by
wrapping it in "----". Because this gives us some extra indentation, we
can remove the one that we have been carrying explicitly. That is, drop
the first tab of indentation on each line. For consistency, make the
same change to the short example shell session further down.
With AsciiDoc, this results in identical rendering before and after this
commit. Asciidoctor now renders this the same as AsciiDoc does.

The indented lines in these example config-file listings are indented
differently by AsciiDoc and Asciidoctor.
Fix this by marking the example config-files as code listings by

git-config.txt pretty consistently uses twelve dashes rather than the
minimum four to spell "----". Let's stick to the file-local convention
there.

There are several graphs in this document. For most of them, we use a
single leading tab to indent the whole graph, and then we use spaces
(possibly eight or more) to align things within the graph.
In the larger graph, we use a different strategy: We use 1-N tabs and
just a small number of spaces (<8). This is how we usually prefer to do
our indenting, but Asciidoctor ends up rendering this differently from
AsciiDoc. Same thing for the if-then-fi examples where the conditional
code is indented by two tabs, which renders differently under AsciiDoc
and Asciidoctor.
Similar to 379805051d ("Documentation: render revisions correctly under
Asciidoctor", 2018-05-06), use an explicit literal block to indicate
that we want to keep the leading whitespace in the tables. Change not
just the ones that render differently, but all of them for consistency.
Because this gives us some extra indentation, we can remove the one that
we have been carrying explicitly. That is, drop the first tab of
indentation on each line. With AsciiDoc, this results in identical
rendering before and after this commit, both for git-merge-base.1 and
git-merge-base.html.
A less intrusive change would be to replace tabs 2-N on each line with
eight spaces. But let's follow the example set by 379805051d, so that we
can use our preferred way of indenting.

The documentation for each of these options contains a list. After the
list, AsciiDoc interprets the continuation as a continuation of the
*list*, not as a continution of the larger block. As a result, we get
too much indentation. Wrap the entire blocks in "--" to fix this. With
Asciidoctor, this commit is a no-op, and the two programs now render
these identically.
These two files share the same problem and indeed, they both document
`--untracked-files` in quite similar ways. I haven't checked to what
extent that is intentional or warranted, and to what extent they have
simply drifted apart. I consider such an investigation and possible
cleanup as out of scope for this commit and this patch series.

The first consumer of pattern-matching filenames was the
.gitignore feature. In that context, storing a list of patterns
as a 'struct exclude_list' makes sense. However, the
sparse-checkout feature then adopted these structures and methods,
but with the opposite meaning: these patterns match the files
that should be included!
It would be clearer to rename this entire library as a "pattern
matching" library, and the callers apply exclusion/inclusion
logic accordingly based on their needs.
This commit renames several methods defined in dir.h to make
more sense with the renamed 'struct exclude_list' to 'struct
pattern_list' and 'struct exclude' to 'struct path_pattern':
* last_exclude_matching() -> last_matching_pattern()
* parse_exclude() -> parse_path_pattern()
In addition, the word 'exclude' was replaced with 'pattern'
in the methods below:
* add_exclude_list()
* add_excludes_from_file_to_list()
* add_excludes_from_file()
* add_excludes_from_blob_to_list()
* add_exclude()
* clear_exclude_list()
A few methods with the word "exclude" remain. These will
be handled seperately. In particular, the method
"is_excluded()" is concretely about the .gitignore file
relative to a specific directory. This is the important
boundary between library and consumer: is_excluded() cares
about .gitignore, but is_excluded() calls
last_matching_pattern() to make that decision.

filter-branch suffers from a deluge of disguised dangers that disfigure
history rewrites (i.e. deviate from the deliberate changes). Many of
these problems are unobtrusive and can easily go undiscovered until the
new repository is in use. This can result in problems ranging from an
even messier history than what led folks to filter-branch in the first
place, to data loss or corruption. These issues cannot be backward
compatibly fixed, so add a warning to both filter-branch and its manpage
recommending that another tool (such as filter-repo) be used instead.
Also, update other manpages that referenced filter-branch. Several of
these needed updates even if we could continue recommending
filter-branch, either due to implying that something was unique to
filter-branch when it applied more generally to all history rewriting
tools (e.g. BFG, reposurgeon, fast-import, filter-repo), or because
something about filter-branch was used as an example despite other more
commonly known examples now existing. Reword these sections to fix
these issues and to avoid recommending filter-branch.
Finally, remove the section explaining BFG Repo Cleaner as an
alternative to filter-branch. I feel somewhat bad about this,
especially since I feel like I learned so much from BFG that I put to
good use in filter-repo (which is much more than I can say for
filter-branch), but keeping that section presented a few problems:
* In order to recommend that people quit using filter-branch, we need
to provide them a recomendation for something else to use that
can handle all the same types of rewrites. To my knowledge,
filter-repo is the only such tool. So it needs to be mentioned.
* I don't want to give conflicting recommendations to users
* If we recommend two tools, we shouldn't expect users to learn both
and pick which one to use; we should explain which problems one
can solve that the other can't or when one is much faster than
the other.
* BFG and filter-repo have similar performance
* All filtering types that BFG can do, filter-repo can also do. In
fact, filter-repo comes with a reimplementation of BFG named
bfg-ish which provides the same user-interface as BFG but with
several bugfixes and new features that are hard to implement in
BFG due to its technical underpinnings.
While I could still mention both tools, it seems like I would need to
provide some kind of comparison and I would ultimately just say that
filter-repo can do everything BFG can, so ultimately it seems that it
is just better to remove that section altogether.

In git-format-patch.txt, we were missing some key user information.
First of all, document the special value of `--base=auto`.
Next, while we're at it, surround option arguments with <> and change
existing names such as "Message-Id" to "message id", which conforms with
how existing documentation is written.
Finally, document the `format.outputDirectory` config and change
`format.coverletter` to use camel case.

The commit-graph feature is now on by default, and is being
written during 'git gc' by default. Typically, Git only writes
a commit-graph when a 'git gc --auto' command passes the gc.auto
setting to actualy do work. This means that a commit-graph will
typically fall behind the commits that are being used every day.
To stay updated with the latest commits, add a step to 'git
fetch' to write a commit-graph after fetching new objects. The
fetch.writeCommitGraph config setting enables writing a split
commit-graph, so on average the cost of writing this file is
very small. Occasionally, the commit-graph chain will collapse
to a single level, and this could be slow for very large repos.
For additional use, adjust the default to be true when
feature.experimental is enabled.

A common scenario is if a user is working on a topic branch and they
wish to make some changes to intermediate commits or autosquash, they
would run something such as
git rebase -i --onto master... master
in order to preserve the merge base. This is useful when contributing a
patch series to the Git mailing list, one often starts on top of the
current 'master'. While developing the patches, 'master' is also
developed further and it is sometimes not the best idea to keep rebasing
on top of 'master', but to keep the base commit as-is.
In addition to this, a user wishing to test individual commits in a
topic branch without changing anything may run
git rebase -x ./test.sh master... master
Since rebasing onto the merge base of the branch and the upstream is
such a common case, introduce the --keep-base option as a shortcut.
This allows us to rewrite the above as
git rebase -i --keep-base master
and
git rebase -x ./test.sh --keep-base master
respectively.
Add tests to ensure --keep-base works correctly in the normal case and
fails when there are multiple merge bases, both in regular and
interactive mode. Also, test to make sure conflicting options cause
rebase to fail. While we're adding test cases, add a missing
set_fake_editor call to 'rebase -i --onto master...side'.
While we're documenting the --keep-base option, change an instance of
"merge-base" to "merge base", which is the consistent spelling.

The Linux kernel receives many patches to the devicetree files each
release. The hunk header for those patches typically show nothing,
making it difficult to figure out what node is being modified without
applying the patch or opening the file and seeking to the context. Let's
add a builtin 'dts' pattern to git so that users can get better diff
output on dts files when they use the diff=dts driver.
The regex has been constructed based on the spec at devicetree.org[1]
and with some help from Johannes Sixt.
