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.
Thanks to Junio C Hamano and Miles Bader for good ideas.

* ml/color-grep:
grep: Colorize selected, context, and function lines
grep: Colorize filename, line number, and separator
Add GIT_COLOR_BOLD_* and GIT_COLOR_BG_*
In configuration files (and "git config --color" command line), we
supported one and only one attribute after foreground and background
color. Accept combinations of attributes, e.g.
[diff.color]
old = red reverse bold

Add GIT_COLOR_BOLD_* macros to set both bold and the color in one
sequence. This saves two characters of output ("ESC [ m", minus ";")
and makes the code more readable.
Add the remaining GIT_COLOR_BG_* macros to make the list complete.
The white and black colors are not included since they look bad on most
terminals.

We emulate color escape codes on Windows by overriding printf, fprintf,
and fputs. Warn developers that these are the only functions that can be
used to print them.

We already have these checks in many printf-type functions that have
prototypes which are in header files. Add these same checks to some
more prototypes in header functions and to static functions in .c
files.

* js/diff-color-words:
Change the spelling of "wordregex".
color-words: Support diff.wordregex config option
color-words: make regex configurable via attributes
color-words: expand docs with precise semantics
color-words: enable REG_NEWLINE to help user
color-words: take an optional regular expression describing words
color-words: change algorithm to allow for 0-character word boundaries
color-words: refactor word splitting and use ALLOC_GROW()
Add color_fwrite_lines(), a function coloring each line individually
We have very featureful color-parsing routines which are
used for color.diff.* and other options. Let's make it
easier to use those routines from other parts of the code.
This patch adds a color_parse_mem() helper function which
takes a length-bounded string instead of a NUL-terminated
one. While the helper is only a few lines long, it is nice
to abstract this out so that:
- callers don't forget to free() the temporary buffer
- right now, it is implemented in terms of color_parse().
But it would be more efficient to reverse this and
implement color_parse in terms of color_parse_mem.
This also changes the error string for an invalid color not
to mention the word "config", since it is not always
appropriate (and when it is, the context is obvious since
the offending config variable is given).
Finally, while we are in the area, we clean up the parameter
names in the declaration of color_parse; the var and value
parameters were reversed from the actual implementation.

We have to set the color before every line and reset it before every
newline. Add a function color_fwrite_lines() which does that for us.

git_config() only had a function parameter, but no callback data
parameter. This assumes that all callback functions only modify
global variables.
With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

This adds an option to help scripts find out color settings from
the configuration file.
git config --get-colorbool color.diff
inspects color.diff variable, and exits with status 0 (i.e. success) if
color is to be used. It exits with status 1 otherwise.
If a script wants "true"/"false" answer to the standard output of the
command, it can pass an additional boolean parameter to its command
line, telling if its standard output is a terminal, like this:
git config --get-colorbool color.diff true
When called like this, the command outputs "true" to its standard output
if color is to be used (i.e. "color.diff" says "always", "auto", or
"true"), and "false" otherwise.
