When the user gives an unknown string to a command that expects to
get a ref, we could be more helpful than just saying "that's not a
ref" and die.
Add helper function help_unknown_ref() to take care of displaying an
error message along with a list of suggested refs the user might
have meant. An interaction with "git merge" might go like this:
$ git merge foo
merge: foo - not something we can merge
Did you mean one of these?
origin/foo
upstream/foo

A couple of commands learn --column option to produce columnar output.
By Nguyễn Thái Ngọc Duy (9) and Zbigniew Jędrzejewski-Szmek (1)
* nd/columns:
tag: add --column
column: support piping stdout to external git-column process
status: add --column
branch: add --column
help: reuse print_columns() for help -a
column: add dense layout support
t9002: work around shells that are unable to set COLUMNS to 1
column: add columnar layout
Stop starting pager recursively
Add column layout skeleton and git-column
|

"help -a" also respects column.ui (and column.help if presents)

We used to underline a header text, like this:
This is a header
----------------
content...
But calculating text length so that the dashes align with the text
could get complicated because the text could be in any charset in
translated Git.
There is no point to use this pseudo underline; simply a blank
line would do and it even makes it easier to read:
This is a header
content...
While at it, give translators more context to translate, e.g.
e.g. "git commands available..." instead of "%s available..."

The two functions defined here are implemented in help.c, so makes more sense
to put the definition of those in help.h instead of in builtin.h.

* ar/autospell:
Add help.autocorrect to enable/disable autocorrecting
git wrapper: DWIM mistyped commands
|

This patch introduces a modified Damerau-Levenshtein algorithm into
Git's code base, and uses it with the following penalties to show some
similar commands when an unknown command was encountered:
swap = 0, insertion = 1, substitution = 2, deletion = 4
A typical output would now look like this:
$ git sm
git: 'sm' is not a git-command. See 'git --help'.
Did you mean one of these?
am
rm
The cut-off is at similarity rating 6, which was empirically determined
to give sensible results.
As a convenience, if there is only one candidate, Git continues under
the assumption that the user mistyped it. Example:
$ git reabse
WARNING: You called a Git program named 'reabse', which does
not exist.
Continuing under the assumption that you meant 'rebase'

Just calculate it where it is needed - it is cheap and trivial,
as all the lengths are already there (stored when creating the
command lists).

This patch splits out git-help's functions to builtin-help.c and leaves
only functions used by other builtins in help.c.
First this removes git-help's functions from libgit which are not
interesting for other builtins, second this makes 'git help help' work
again.

Make load_command_list() capable of filtering for a given prefix and
loading into a pair of "struct cmdnames" supplied by the caller.
Make the static add_cmdname(), exclude_cmds() and is_in_cmdlist()
functions non-static.
Make list_commands() accept a custom title, and work from a pair of
"struct cmdnames" supplied by the caller.
