required by old timers that still rely on the age old promise that
prepending "git --exec-path" output to PATH early in their script
will keep the "git-foo" calls they wrote working.

The resizeclistpanes and resizecdetpanes procedures attempt to keep
the horizontal proportions of the panes of the gitk window
approximately constant when the gitk window is resized. However, if
the size is reduced enough that an existing sash position would go
outside the window, Tk moves the sash to the left to keep it inside
the window (without moving other sash positions to keep the
proportions). This happens before these resize procedures get
control, and so they work with incorrect proportions.
To fix this, we record the sash positions we set previously and use
those previously-set sash positions rather than the current sash
positions when computing the proportions.

The source code is a mix of tabs and spaces. The indentation style
currently is four spaces per indent level but uses tabs every other
level (at eight spaces). Fix this inconsistent spacing and tabbing by
just using a space-indent for everything.
This was done mechanically by running:
$ expand -i gitk >gitk.new
$ mv gitk.new gitk
This patch should be empty with `--ignore-all-space`.

Way back in f9b8908b (commit.c: use generation numbers for
in_merge_bases(), 2018-05-01), a heuristic was used to short-circuit
the in_merge_bases() walk. This works just fine as long as the
caller is checking only two commits, but when there are multiple,
there is a possibility that this heuristic is _very wrong_.
Some code moves since then has changed this method to
repo_in_merge_bases_many() inside commit-reach.c. The heuristic
computes the minimum generation number of the "reference" list, then
compares this number to the generation number of the "commit".
In a recent topic, a test was added that used in_merge_bases_many()
to test if a commit was reachable from a number of commits pulled
from a reflog. However, this highlighted the problem: if any of the
reference commits have a smaller generation number than the given
commit, then the walk is skipped _even if there exist some with
higher generation number_.
This heuristic is wrong! It must check the MAXIMUM generation number
of the reference commits, not the MINIMUM.
This highlights a testing gap. t6600-test-reach.sh covers many
methods in commit-reach.c, including in_merge_bases() and
get_merge_bases_many(), but since these methods either restrict to
two input commits or actually look for the full list of merge bases,
they don't check this heuristic!
Add a possible input to "test-tool reach" that tests
in_merge_bases_many() and add tests to t6600-test-reach.sh that
cover this heuristic. This includes cases for the reference commits
having generation above and below the generation of the input commit,
but also having maximum generation below the generation of the input
commit.
The fix itself is to swap min_generation with a max_generation in
repo_in_merge_bases_many().

Commands such as
$ git pull --rebase --recurse-submodules --quiet
produce non-quiet output from the merge or rebase. Pass the --quiet
option down when invoking "rebase" and "merge".
Also fix the parsing of git submodule update -v.
When e84c3cf3 (git-submodule.sh: accept verbose flag in cmd_update
to be non-quiet, 2018-08-14) taught "git submodule update" to take
"--quiet", it apparently did not know how ${GIT_QUIET:+--quiet}
works, and reviewers seem to have missed that setting the variable
to "0", rather than unsetting it, still results in "--quiet" being
passed to underlying commands.

The OFFSETOF_VAR(var, member) macro is implemented in terms of
offsetof(typeof(*var), member) with compilers that know typeof(),
but its fallback implemenation compares &(var->member) and (var) and
count the distance in bytes, i.e.
((uintptr_t)&(var)->member - (uintptr_t)(var))
MSVC's runtime check, when fed an uninitialized 'var', flags this as
a use of an uninitialized variable (and that is legit---uninitialized
contents of 'var' is subtracted) in a debug build.
After auditing all 6 uses of OFFSETOF_VAR(), 1 of them does feed a
potentially uninitialized 'var' to the macro in the beginning of the
for() loop:
#define hashmap_for_each_entry(map, iter, var, member) \
for (var = hashmap_iter_first_entry_offset(map, iter, \
OFFSETOF_VAR(var, member)); \
var; \
var = hashmap_iter_next_entry_offset(iter, \
OFFSETOF_VAR(var, member)))
We can work around this by making sure that var has _some_ value
when OFFSETOF_VAR() is called. Strictly speaking, it invites
undefined behaviour to use NULL here if we end up with pointer
comparison, but MSVC runtime seems to be happy with it, and most
other systems have typeof() and don't even need pointer comparison
fallback code.

It is a lot more convenient to use than having to specify the
configuration in CMake manually (does not matter whether using the
command-line or CMake's GUI).
While at it, recommend using `contrib/buildsystems/out/` as build
directory also in the part that talks about running CMake manually.

The idea of having CMake support in Git's source tree is to enable
contributors on Windows to start contributing with little effort. To
that end, we just added some sensible defaults that will let users open
the worktree in Visual Studio and start building.
This expects the dependencies (such as zlib) to be available already,
though. If they are not available, we expect the user to run
`compat/vcbuild/vcpkg_install.bat`.
Rather than requiring this step to be manual, detect the situation and
run it as part of the CMake configuration step.
Note that this obviously only applies to the scenario when we want to
compile in Visual Studio (i.e. with MS Visual C), not with GCC.
Therefore, we guard this new code block behind the `MSVC` conditional.
This concludes our journey to make it as effortless as possible to start
developing Git in Visual Studio: all the developer needs to do is to
clone Git's repository, open the worktree via `File>Open>Folder...` and
wait for CMake to finish configuring.

The append_signoff() function takes an "ignore_footer"
argument, which specifies a number of bytes at the end of
the message buffer which should not be considered (they
cannot contain trailers, and the trailer is spliced in
before them).
But to find the existing trailers, it calls into
has_conforming_trailer(). That function takes an
ignore_footer parameter, but since 967dfd4d56 (sequencer:
use trailer's trailer layout, 2016-11-02) the parameter is
completely ignored.
The trailer interface we're using takes a single string,
with no option to tell it to use part of the string.
However, since we have a mutable strbuf, we can work around
this by simply overwriting (and later restoring) the
boundary with a NUL.
I'm not sure if this can actually trigger a bug in practice.
It's easy to get a non-zero ignore_footer by doing something
like this:
git commit -F - --cleanup=verbatim <<-EOF
subject
body
Signed-off-by: me
# this looks like a comment, but is actually in the
# message! That makes the earlier s-o-b fake.
EOF
git commit --amend -s
There git-commit calls ignore_non_trailer() to count up the
"#" cruft, which becomes the ignore_footer header. But it
works even without this patch! That's because the trailer
code _also_ calls ignore_non_trailer() and skips the cruft,
too. So it happens to work because the only callers with a
non-zero ignore_footer are using the exact same function
that the trailer parser uses internally.
And that seems true for all of the current callers, but
there's nothing guaranteeing it. We're better off only
feeding the correct buffer to the trailer code in the first
place.

The sparse-checkout passes along argv and argc to its sub-command helper
functions. Many of these sub-commands do not yet take any command-line
options, and ignore those parameters.
Let's instead add empty option lists and make sure we call

like:
git sparse-checkout list --nonsense
which currently just silently ignores the unknown option.

When we switched to using an external git-commit call in b0a3186140
(sequencer: simplify root commit creation, 2019-08-19), this function
didn't need to care about the repository object any more.
Arguably we could be passing along the repository path to the external
git-commit by using "--git-dir=r->path" here. But for the most part the
sequencer code relies on sub-process finding the same repository we're
already in (using the same environment variables or discovery process we
did). But we don't have a convenient interface for doing so, and there's
no indication that we need to. Let's just drop the unused parameter for
now.

In the spirit of 517fe807d6 (assert NOARG/NONEG behavior of

expectations and future-proof the code.

We use OPT_CALLBACK_F() to call the option_parse_type() callback,
passing it the address of "cmdmode" as the value to write to. But the
callback doesn't look at opt->value at all, and instead writes to a
global variable.
This works out because that's the same global variable we happen to pass
in, but it's rather confusing. Let's use the passed-in value instead.

Many functions take an argv/argc pair, but never actually look at argc.
This makes it useless at best (we use the NULL sentinel in argv to find
the end of the array), and misleading at worst (what happens if the argc
count does not match the argv NULL?).
In each of these instances, the argv NULL does match the argc count, so
there are no bugs here. But let's tighten the interfaces to make it
harder to get wrong (and to reduce some -Wunused-parameter complaints).
