In some use cases it is not desirable that the diff family considers
submodules that only contain untracked content as dirty. This may happen
e.g. when the submodule is not under the developers control and not all
build generated files have been added to .gitignore by the upstream
developers. Using the "untracked" parameter for the "--ignore-submodules"
option disables checking for untracked content and lets git diff report
them as changed only when they have new commits or modified content.
Sometimes it is not wanted to have submodules show up as changed when they
just contain changes to their work tree. An example for that are scripts
which just want to check for submodule commits while ignoring any changes
to the work tree. Also users having large submodules known not to change
might want to use this option, as the - sometimes substantial - time it
takes to scan the submodule work tree(s) is saved.

This teaches the --color-words engine a more general interface that
supports two new modes:
* --word-diff=plain, inspired by the 'wdiff' utility (most similar to
'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+}
* --word-diff=porcelain, which generates an ad-hoc machine readable
format:
- each diff unit is prefixed by [-+ ] and terminated by newline as
in unified diff
- newlines in the input are output as a line consisting only of a
tilde '~'
Both of these formats still support color if it is enabled, using it
to highlight the differences. --color-words becomes a synonym for
--word-diff=color, which is the color-only format. Also adds some
compatibility/convenience options.

Make git-branch, git-show-branch, git-grep, and all the diff-based
programs accept an optional argument <when> for --color. The argument
is a colorbool: "always", "never", or "auto". If no argument is given,
"always" is used; --no-color is an alias for --color=never. This makes
the command-line interface consistent with other GNU tools, such as `ls'
and `grep', and with the git-config color options. Note that, without
an argument, --color and --no-color work exactly as before.
To implement this, two internal changes were made:
1. Allow the first argument of git_config_colorbool() to be NULL,
in which case it returns -1 if the argument isn't "always", "never",
or "auto".
2. Add OPT_COLOR_FLAG(), OPT__COLOR(), and parse_opt_color_flag_cb()
to the option parsing library. The callback uses
git_config_colorbool(), so color.h is now a dependency
of parse-options.c.

Jeff King recently reinstated -p to suppress the default diffstat
(as -p used to work before 68daa64, about 14 months ago).
However, -p is also needed in combination with certain options
(e.g. --stat or --numstat) in order to produce any patch at all.
The documentation does not mention this.
Since the purpose of format-patch is to produce a patch that
can be emailed, it does not make sense that certain combination
of options will suppress the generation of the patch itself.
Therefore:
* Update 'git format-patch' to always generate a patch.
* Since the --name-only, --name-status, and --check suppresses
the generation of the patch, disallow those options,
and remove the description of them in the documentation.
* Remove the reference to -p in the description of -U.
* Remove the descriptions of the options that are synonyms for -p
plus another option (--patch-with-raw and --patch-with-stat).
* While at it, slightly tweak the description of -p itself
to say that it generates "plain patches", so that you can
think of -p as "plain patch" as an mnemonic aid.

In some applications, words are not delimited by white space. To
allow for that, you can specify a regular expression describing
what makes a word with

Note that words cannot contain newline characters.
As suggested by Thomas Rast, the words are the exact matches of the

Note that a regular expression beginning with a '^' will match only
a word at the beginning of the hunk, not a word at the beginning of

Signed-off-by: Junio C Hamano <gitster@pobox.com>
This adds --relative option to the diff family. When you start
from a subdirectory:
$ git diff --relative
shows only the diff that is inside your current subdirectory,
and without $prefix part. People who usually live in
subdirectories may like it.
There are a few things I should also mention about the change:
- This works not just with diff but also works with the log
family of commands, but the history pruning is not affected.
In other words, if you go to a subdirectory, you can say:
$ git log --relative -p
but it will show the log message even for commits that do not
touch the current directory. You can limit it by giving
pathspec yourself:
$ git log --relative -p .
This originally was not a conscious design choice, but we
have a way to affect diff pathspec and pruning pathspec
independently. IOW "git log --full-diff -p ." tells it to
prune history to commits that affect the current subdirectory
but show the changes with full context. I think it makes
more sense to leave pruning independent from --relative than
the obvious alternative of always pruning with the current
subdirectory, which would break the symmetry.
- Because this works also with the log family, you could
format-patch a single change, limiting the effect to your
subdirectory, like so:
$ cd gitk-git
$ git format-patch -1 --relative 911f1eb
But because that is a special purpose usage, this option will
never become the default, with or without repository or user
preference configuration. The risk of producing a partial
patch and sending it out by mistake is too great if we did
so.
- This is inherently incompatible with --no-index, which is a
bolted-on hack that does not have much to do with git
itself. I didn't bother checking and erroring out on the
combined use of the options, but probably I should.
