The combined diff format for merges will only list one filename, even if
rename or copy detection is active. For example, with raw format one
might see:
::100644 100644 100644 fabadb8cc95eb04866510 MM describe.c
::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM bar.sh
::100644 100644 100644 e07d6c5 9042e82 ee91881 RR phooey.c
This doesn't let us know what the original name of bar.sh was in the
first parent, and doesn't let us know what either of the original names
of phooey.c were in either of the parents. In contrast, for non-merge
commits, raw format does provide original filenames (and a rename score
to boot). In order to also provide original filenames for merge
commits, add a --combined-all-paths option (which must be used with
either -c or --cc, and is likely only useful with rename or copy
detection active) so that we can print tab-separated filenames when
renames are involved. This transforms the above output to:
::100644 100644 100644 fabadb8cc95eb04866510 MM desc.c desc.c desc.c
::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM foo.sh bar.sh bar.sh
::100644 100644 100644 e07d6c5 9042e82 ee91881 RR fooey.c fuey.c phooey.c
Further, in patch format, this changes the from/to headers so that
instead of just having one "from" header, we get one for each parent.
For example, instead of having
--- a/phooey.c
+++ b/phooey.c
we would see
--- a/fooey.c
--- a/fuey.c
+++ b/phooey.c

A regression was introduced in 557a5998d (submodule: remove
gitmodules_config, 2017-08-03) to how attribute processing was handled
in bare repositories when running the diff-tree command.
By default the attribute system will first try to read ".gitattribute"
files from the working tree and then falls back to reading them from the
index if there isn't a copy checked out in the worktree. Prior to
557a5998d the index was read as a side effect of the call to
'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.
Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.
Fix this by explicitly reading the index during the setup of diff-tree.

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.

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.

The diff porcelain uses git_diff_ui_config to set
porcelain-ish config options, like automatically turning on
color. The plumbing specifically avoids calling this
function, since it doesn't want things like automatic color
or rename detection.
However, some diff options should be set for both plumbing
and porcelain. For example, one can still turn on color in
git-diff-files using the --color command line option. This
means we want the color config from color.diff.* (so that
once color is on, we use the user's preferred scheme), but
_not_ the color.diff variable.
We split the diff config into "ui" and "basic", where
"basic" is suitable for use by plumbing (so _most_ things
affecting the output should still go into the "ui" part).

Any git command that expects to work in a subdirectory of a project, and
that reads the git config files (which is just about all of them) needs to
make sure that it does the "setup_git_directory()" call before it tries to
read the config file.

There currently is an unfortunate circular dependency between
what init_revisions (the command line revision specification
parser) does and setting up the log and diff options. The
function uses setup_git_directory() to find the root of the
project relative to the current directory and calls diff_setup()
to prepare diff generation. However, some of the things that
diff_setup() does needs to depend on the configuration variable,
which needs to be read after setup_git_directory() is called.
This patch is a low impact workaround. It first lets
init_revisions() to run and do its thing, then uses git_config()
and diff_setup() after it returns, so that configuration
variables that affects the diff operation can be used from
subdirectories.

The Porcelainish has become so much usable as the UI that there
is not much reason people should be using the core programs by
hand anymore. At this point we are better off making the
behaviour of the core programs predictable by keeping them
unaffected by the configuration variables. Otherwise they will
become very hard to use as reliable building blocks.
For example, "git-commit -a" internally uses git-diff-files to
figure out the set of paths that need to be updated in the
index, and we should never allow diff.renames that happens to be
in the configuration to interfere (or slow down the process).
The UI level configuration such as showing renamed diff and
coloring are still honored by the Porcelainish ("git log" family
and "git diff"), but not by the core anymore.
