6dcca4d0ea Documentation/technical: avoid stray backslash in parse-options API docs
Due to some unpleasant interaction between the `quote', 'italics',
and `monospace` rules, a certain paragraph ends up rendered like so:

	‘short` is a character for the short option
	  (e.g. <tt>'e\’</tt> for <tt>-e</tt>, use <tt>0</tt> to omit),

Use the {apostrophe} to avoid this.

While at it, escape "->" strings: they are meant as a literal
two-character C operator, not a right-pointing arrow.

73e9da0196 Add an optional argument for --color 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.

df217ed643 parse-opts: add OPT_FILENAME and transition builtins
Commit dbd0f5c (Files given on the command line are relative to $cwd,
2008-08-06) introduced parse_options_fix_filename() as a minimal fix.
OPT_FILENAME is intended to be a more robust fix for the same issue.
OPT_FILENAME and its associated enum OPTION_FILENAME are used to
represent filename options within the parse options API.

This option is similar to OPTION_STRING. If --no is prefixed to the
option the filename is unset. If no argument is given and the default
value is set, the filename is set to the default value. The difference
is that the filename is prefixed with the prefix passed to
parse_options() (or parse_options_start()).

Update git-apply, git-commit, git-fmt-merge-msg, and git-tag to use
OPT_FILENAME with their filename options. Also, rename
parse_options_fix_filename() to fix_filename() as it is no longer
extern.

3778292017 parse-opts: prepare for OPT_FILENAME
To give OPT_FILENAME the prefix, we pass the prefix to parse_options()
which passes the prefix to parse_options_start() which sets the prefix
member of parse_opts_ctx accordingly. If there isn't a prefix in the
calling context, passing NULL will suffice.

2f4b97f910 parseopt: add OPT_NEGBIT
Add OPTION_NEGBIT and OPT_NEGBIT, mirroring OPTION_BIT and OPT_BIT.
OPT_NEGBIT can be used together with OPT_BIT to define two options
that cancel each other out.

Note: this patch removes the reminder from the test script because
it adds a test for --no-or4 and there already was one for --or4.

0d260f9a09 parseopt: prevent KEEP_UNKNOWN and STOP_AT_NON_OPTION from being used together
As suggested by Junio, disallow the flags PARSE_OPT_KEEP_UNKNOWN and
PARSE_OPT_STOP_AT_NON_OPTION to be turned on at the same time, as a
value of an unknown option could be mistakenly classified as a
non-option, stopping the parser early.  E.g.:

	git cmd --known --unknown value arg0 arg1

The parser should have stopped at "arg0", but it already stops at
"value".

This patch makes parse_options() die if the two flags are used in
combination.

530e741c72 Start preparing the API documents.
Most of them are still stubs, but the procedure to build the HTML
documentation, maintaining the index and installing the end product are
there.

I placed names of people who are likely to know the most about the topic
in the stub files, so that volunteers will know whom to ask questions as
needed.
