In the implementation of "git difftool", there is a case where the
user wants to start viewing the diffs at a specific path and
continue on to the rest, optionally wrapping around to the
beginning. Since it is somewhat cumbersome to implement such a
feature as a post-processing step of "git diff" output, let's
support it internally with two new options.
- "git diff --rotate-to=C", when the resulting patch would show
paths A B C D E without the option, would "rotate" the paths to
shows patch to C D E A B instead. It is an error when there is
no patch for C is shown.
- "git diff --skip-to=C" would instead "skip" the paths before C,
and shows patch to C D E. Again, it is an error when there is no
patch for C is shown.
- "git log [-p]" also accepts these two options, but it is not an
error if there is no change to the specified path. Instead, the
set of output paths are rotated or skipped to the specified path
or the first path that sorts after the specified path.

The `diff-files' command and related commands which call the function
`cmd_diff_files()', consider the "intent-to-add" files as a part of the
index when comparing the work-tree against it. This was previously
addressed in commits [1] and [2] by turning the option
`--ita-invisible-in-index' (introduced in [3]) on by default.
For `diff-files' (and `add -p' as a consequence) to show the i-t-a
files as as new, `ita_invisible_in_index' will be enabled by default
here as well.

Now that the submodule-config subsystem can lazily read the gitmodules
file we no longer need to explicitly pre-read the gitmodules by calling
'gitmodules_config()' so let's remove it.

Fix configuration codepath to pay proper attention to commondir
that is used in multi-worktree situation, and isolate config API
into its own header file.
* bw/config-h:
config: don't implicitly use gitdir or commondir
config: respect commondir
setup: teach discover_git_directory to respect the commondir
config: don't include config.h by default
config: remove git_config_iter
config: create config.h
"git $cmd -h" for builtin commands calls the implementation of the
command (i.e. cmd_$cmd() function) without doing any repository
set-up, and the commands that expect RUN_SETUP is done by the Git
potty needs to be prepared to show the help text without barfing.
* jk/consistent-h:
t0012: test "-h" with builtins
git: add hidden --list-builtins option
version: convert to parse-options
diff- and log- family: handle "git cmd -h" early
submodule--helper: show usage for "-h"
remote-{ext,fd}: print usage message on invalid arguments
upload-archive: handle "-h" option early
credential: handle invalid arguments earlier
Stop including config.h by default in cache.h. Instead only include
config.h in those files which require use of the config system.

"git $builtin -h" bypasses the usual repository setup and calls the
cmd_$builtin() function, expecting it to show the help text.
Unfortunately the commands in the log- and the diff- family want to
call into the revisions machinery, which by definition needs to have
a repository already discovered. Strictly speaking, they may not
need a repository only for parsing "-h", but it is a good discipline
to future-proof codepath to ensure that setup_revisions() is called
after we know that a repository is there.
Handle the "git $builtin -h" special case very early in these
commands to work around potential issues.

This matches how the diff Porcelain works. It makes the plumbing commands
respect diff's configuration options, such as indentHeuristic, because
init_revisions() calls diff_setup() which fills in the diff_options struct.

When running diff commands, a pathspec containing decomposed
unicode code points is not converted to precomposed unicode form
under Mac OS X, but we normalize the paths in the index and the
history to precomposed form on that platform. As a result, the
pathspec would not match and no diff is shown.
Unlike many builtin commands, the "diff" family of commands do
not use parse_options(), which is how other builtin commands
indirectly call precompose_argv() to normalize argv[] into
precomposed form on Mac OSX. Teach these commands to call
precompose_argv() themselves.
Note that precomopose_argv() normalizes not just paths but all
command line arguments, so things like "git diff -G $string"
when $string has the decomposed form would first be normalized
into the precomposed form and would stop hitting the same string
in the decomposed form in the diff output with this change.
It is not a problem per-se, as "log" family of commands already use
parse_options() and call precompose_argv()--we can think of this
change as making the "diff" family of commands behave in a similar
way as the commands in the "log" family.

This patch puts the usage info strings that were not already in docopt-
like format into docopt-like format, which will be a litle easier for
end users and a lot easier for translators. Changes include:
- Placing angle brackets around fill-in-the-blank parameters
- Putting dashes in multiword parameter names
- Adding spaces to [-f|--foobar] to make [-f | --foobar]
- Replacing <foobar>* with [<foobar>...]

The .gitmodules file is parsed for "submodule.<name>.ignore" entries
before looking for them in .git/config. Thus settings found in .git/config
will override those from .gitmodules, thereby allowing the local developer
to ignore settings given by the remote side while also letting upstream
set defaults for those users who don't have special needs.

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of
[torvalds@nehalem git]$ em buil<tab>
Display all 180 possibilities? (y or n)
[torvalds@nehalem git]$ em builtin-sh
builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c
builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o
[torvalds@nehalem git]$ em builtin-shor<tab>
builtin-shortlog.c builtin-shortlog.o
[torvalds@nehalem git]$ em builtin-shortlog.c
you get
[torvalds@nehalem git]$ em buil<tab> [type]
builtin/ builtin.h
[torvalds@nehalem git]$ em builtin [auto-completes to]
[torvalds@nehalem git]$ em builtin/sh<tab> [type]
shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o
[torvalds@nehalem git]$ em builtin/sho [auto-completes to]
[torvalds@nehalem git]$ em builtin/shor<tab> [type]
shortlog.c shortlog.o
[torvalds@nehalem git]$ em builtin/shortlog.c
which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.
NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead. I think bash has some cut-off
around 100 choices or something.
So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion. But you can
simulate that by using 'ls' instead, or something similar.
