f45db831c1 completion: keep other config var completion in camelCase
The last patch makes "git config <tab>" shows camelCase names because
that's what's in the source: config.txt. There are still a couple
manual var completion in this code. Let's make them follow the naming
convention as well.

In theory we could automate this part too because we have the
information. But let's stick to one step at a time and leave this for
later.

e17ca92637 completion: drop the hard coded list of config vars
The new help option --config-for-completion is a machine friendlier
version of --config where all the placeholders and wildcards are
dropped, leaving only the good, completable prefixes for
git-completion.bash to consume.

3301d36b29 completion: add and use --list-cmds=alias
By providing aliases via --list-cmds=, we could simplify command
collection code in the script. We only issue one git command. Before
this patch that is "git config", after it's "git --list-cmds=". In
"git help" completion case we actually reduce one "git" process (for
getting guides) but that call was added in this series so it does not
really count.

A couple of bash functions are removed because they are not needed
anymore. __git_compute_all_commands() and $__git_all_commands stay
because they are still needed for completing pager.* config and
without "alias" group, the result is still cacheable.

There is a slight (good) change in _git_help() with this patch: before
"git help <tab>" shows external commands (as in _not_ part of git) as
well as part of $__git_all_commands. We have finer control over
command listing now and can exclude that because we can't provide a
man page for external commands anyway.

84a9713106 completion: let git provide the completable command list
Instead of maintaining a separate list of command classification,
which often could go out of date, let's centralize the information
back in git.

While the function in git-completion.bash implies "list porcelain
commands", that's not exactly what it does. It gets all commands (aka
--list-cmds=main,others) then exclude certain non-porcelain ones. We
could almost recreate this list two lists list-mainporcelain and
others. The non-porcelain-but-included-anyway is added by the third
category list-complete.

Note that the current completion script incorrectly classifies
filter-branch as porcelain and t9902 tests this behavior. We keep it
this way in t9902 because this test does not really care which
particular command is porcelain or plumbing, they're just names.

6bb2dc0b94 completion: implement and use --list-cmds=main,others
This is part of the effort to break down and provide commands by
category in machine-readable form. This could be helpful later on when
completion script switches to use --list-cmds for selecting
completable commands. It would be much easier for the user to choose
to complete _all_ commands instead of the default selection by passing
different values to --list-cmds in git-completino.bash.

While at there, replace "git help -a" in git-completion.bash with
--list-cmds since it's better suited for this task.

085e2ee0e6 completion: load completion file for external subcommand
Adding external subcommands to Git is as easy as to put an executable
file git-foo into PATH. Packaging such subcommands for a Linux
distribution can be achieved by unpacking the executable into /usr/bin
of the user's system. Adding system-wide completion scripts for new
subcommands, however, can be a bit tricky.

Since bash-completion started to use dynamical loading of completion
scripts since v1.90 (preview of v2.0), it is no longer sufficient to
drop a completion script of a subcommand into the standard completions
path, /usr/share/bash-completion/completions, since this script will not
be loaded if called as a git subcommand.

For example, look at https://bugs.gentoo.org/544722. To give a short
summary: The popular git-flow subcommand provides a completion script,
which gets installed as /usr/share/bash-completion/completions/git-flow.

If you now type into a Bash shell:

    git flow <TAB>

You will not get any completions, because bash-completion only loads
completions for git and git has no idea that git-flow is defined in
another file. You have to load this script manually or trigger the
dynamic loader with:

    git-flow <TAB> # Please notice the dash instead of whitespace

This will not complete anything either, because it only defines a Bash
function, without generating completions. But now the correct completion
script has been loaded and the first command can use the completions.

So, the goal is now to teach the git completion script to consider the
possibility of external completion scripts for subcommands, but of
course without breaking current workflows.

I think the easiest method is to use a function that was defined by
bash-completion v1.90, namely _completion_loader. It will take care of
loading the correct script if present. Afterwards, the git completion
script behaves as usual.

_completion_loader was introduced in commit 20c05b43 of bash-completion
(https://github.com/scop/bash-completion.git) back in 2011, so it should
be available in even older LTS distributions. This function searches for
external completion scripts not only in the default path
/usr/share/bash-completion/completions, but also in the user's home
directory via $XDG_DATA_HOME and in a user specified directory via
$BASH_COMPLETION_USER_DIR.

The only "drawback" (if it even can be called as such) is, that if
_completion_loader does not find a completion script, it automatically
registers a minimal function for basic path completion. In practice,
however, this will not matter, because in this case the given command is
a git command in its dashed form, e.g. 'git-diff-index', and those have
been deprecated for a long time.

This way we can leverage bash-completion's dynamic loading for git
subcommands and make it easier for developers to distribute custom
completion scripts.

279ffad17d coccinelle: avoid wrong transformation suggestions from commit.cocci
The semantic patch 'contrib/coccinelle/commit.cocci' added in
2e27bd7731 (treewide: replace maybe_tree with accessor methods,
2018-04-06) is supposed to "ensure that all references to the
'maybe_tree' member of struct commit are either mutations or accesses
through get_commit_tree()".  So get_commit_tree() clearly must be able
to directly access the 'maybe_tree' member, and 'commit.cocci' has a
bit of a roundabout workaround to ensure that get_commit_tree()'s
direct access in its return statement is not transformed: after all
references to 'maybe_tree' have been transformed to a call to
get_commit_tree(), including the reference in get_commit_tree()
itself, the last rule transforms back a 'return get_commit_tree()'
statement, back then found only in get_commit_tree() itself, to a
direct access.

Unfortunately, already the very next commit shows that this workaround
is insufficient: 7b8a21dba1 (commit-graph: lazy-load trees for
commits, 2018-04-06) extends get_commit_tree() with a condition
directly accessing the 'maybe_tree' member, and Coccinelle with
'commit.cocci' promptly detects it and suggests a transformation to
avoid it.  This transformation is clearly wrong, because calling
get_commit_tree() to access 'maybe_tree' _in_ get_commit_tree() would
obviously lead to recursion.  Furthermore, the same commit added
another, more specialized getter function get_commit_tree_in_graph(),
whose legitimate direct access to 'maybe_tree' triggers a similar
wrong transformation suggestion.

Exclude both of these getter functions from the general rule in
'commit.cocci' that matches their direct accesses to 'maybe_tree'.
Also exclude load_tree_for_commit(), which, as static helper funcion
of get_commit_tree_in_graph(), has legitimate direct access to
'maybe_tree' as well.

The last rule transforming back 'return get_commit_tree()' statements
to direct accesses thus became unnecessary, remove it.

8f6aed71d2 rebase: introduce the --rebase-merges option
Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?

The original attempt to answer this was: git rebase --preserve-merges.

However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.

Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.

The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.

This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.

Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.

Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.

That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.

With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

94408dc71c completion: reduce overhead of clearing cached --options
To get the names of all '$__git_builtin_*' variables caching --options
of builtin commands in order to unset them, 8b0eaa41f2 (completion:
clear cached --options when sourcing the completion script,
2018-03-22) runs a 'set |sed s///' pipeline.  This works both in Bash
and in ZSH, but has a higher than necessary overhead with the extra
processes.

In Bash we can do better: run the 'compgen -v __gitcomp_builtin_'
builtin command, which lists the same variables, but without a
pipeline and 'sed' it can do so with lower overhead.
ZSH will still continue to run that pipeline.

This change also happens to work around an issue in the default Bash
version shipped in macOS (3.2.57), reported by users of the Powerline
shell prompt, which was triggered by the same commit 8b0eaa41f2 as
well.  Powerline uses several Unicode Private Use Area code points to
represent some of its pretty text UI elements (arrows and what not),
and these are stored in the $PS1 variable.  Apparently the 'set'
builtin of said Bash version on macOS has issues with these code
points, and produces garbled output where Powerline's special symbols
should be in the $PS1 variable.  This, in turn, triggers the following
error message in the downstream 'sed' process:

  sed: RE error: illegal byte sequence

Other Bash versions, notably 4.4.19 on macOS via homebrew (i.e. a

slightly earlier version, though on a different platform) are not
affected.  ZSH in macOS (the versions shipped by default or installed
via homebrew) or on other platforms isn't affected either.

With this patch neither the 'set' builtin is invoked to print garbage,
nor 'sed' to choke on it.

6d5ed4836d git{,-blame}.el: remove old bitrotting Emacs code
The git-blame.el mode has been superseded by Emacs's own
vc-annotate (invoked by C-x v g). Users of the git.el mode are now
much better off using either Magit or the Git backend for Emacs's own
VC mode.

These modes were added over 10 years ago when Emacs's own Git support
was much less mature, and there weren't other mature modes in the wild
or shipped with Emacs itself.

These days these modes have few if any users, and users of git aren't
well served by us shipping these (some OS's install them alongside git
by default, which is confusing and leads users astray).

So let's remove these per Alexandre Julliard's message to the
ML[1]. If someone still wants these for some reason they're better
served by hosting these elsewhere (e.g. on ELPA), instead of us
distributing them with git.

However, since downstream packagers such as Debian are packaging this
as git-el it's less disruptive to still carry these files as Elisp
code that'll error out with a message suggesting alternatives, rather
than drop the files entirely[2].

Then rather than receive a cryptic load error when they upgrade
existing users will get an error directing them to the README file, or
to just stop requiring these modes. I think it makes sense to link to
GitHub's hosting of contrib/emacs/README (which'll be updated by the
time users see this) so they don't have to hunt down the packaged
README on their local system.

78a2d21231 completion: improve ls-files filter performance
From the output of ls-files, we remove all but the leftmost path
component and then we eliminate duplicates. We do this in a while loop,
which is a performance bottleneck when the number of iterations is large
(e.g. for 60000 files in linux.git).

$ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git

real    0m11.876s
user    0m4.685s
sys     0m6.808s

Replacing the loop with the cut command improves performance
significantly:

$ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git

real    0m1.372s
user    0m0.263s
sys     0m0.167s

The measurements were done with Msys2 bash, which is used by Git for
Windows.

When filtering the ls-files output we take care not to touch absolute
paths. This is redundant, because ls-files will never output absolute
paths. Remove the unnecessary operations.

The issue was reported here:

49eb8d39c7 Remove contrib/examples/*
There were some side discussions at Git Merge this year about how we
should just update the README to tell users they can dig these up from
the history if the need them, do that.

Looking at the "git log" for this directory we get quite a bit more
patch churn than we should here, mainly from things fixing various
tree-wide issues.

There's also confusion on the list occasionally about how these should
be treated, "Re: [PATCH 1/4] stash: convert apply to
builtin" (<CA+CzEk9QpmHK_TSBwQfEedNqrcVSBp3xY7bdv1YA_KxePiFeXw@mail.gmail.com>)

9f642a7169 completion: add --option completion for most builtin commands
Many builtin commands use parseopt which can expose the option list
via --git-completion-helper but do not have explicit support in
git-completion.bash. This patch detects those commands and uses
__gitcomp_builtin for option completion.

This does not pollute the command name completion though. "git <tab>"
will show you the same set as before. This only kicks in when you type
the correct command name.

8b0eaa41f2 completion: clear cached --options when sourcing the completion script
The established way to update the completion script in an already
running shell is to simply source it again: this brings in any new
--options and features, and clears caching variables.  E.g. it clears
the variables caching the list of (all|porcelain) git commands, so
when they are later lazy-initialized again, then they will list and
cache any newly installed commmands as well.

Unfortunately, since d401f3debc (git-completion.bash: introduce
__gitcomp_builtin, 2018-02-09) and subsequent patches this doesn't
work for a lot of git commands' options.  To eliminate a lot of
hard-to-maintain hard-coded lists of options, those commits changed
the completion script to use a bunch of programmatically created and
lazy-initialized variables to cache the options of those builtin
porcelain commands that use parse-options.  These variables are not
cleared upon sourcing the completion script, therefore they continue
caching the old lists of options, even when some commands recently
learned new options or when deprecated options were removed.

Always 'unset' these variables caching the options of builtin commands
when sourcing the completion script.

Redirect 'unset's stderr to /dev/null, because ZSH's 'unset' complains
if it's invoked without any arguments, i.e. no variables caching
builtin's options are set.  This can happen, if someone were to source
the completion script twice without completing any --options in
between.  Bash stays silent in this case.

Add tests to ensure that these variables are indeed cleared when the
completion script is sourced; not just the variables caching options,
but all other caching variables, i.e. the variables caching commands,
porcelain commands and merge strategies as well.
