Timo Hirvonen f37399e6b0 diff: Support both attributes and colors
Make it possible to set both colors and a attribute for diff colors.
Background colors are supported too.

Syntax is now:

	[attr] [fg [bg]]
	[fg [bg]] [attr]

Empty value is same as "normal normal", ie use default colors.  The new
syntax is backwards compatible.

Shawn Pearce 344c52aee5 Avoid C99 initializers
In a handful places, we use C99 structure and array
initializers, which some compilers do not support.

This can be handy when you are trying to compile GIT on a
Solaris system that has an older C compiler, for example.

Junio C Hamano 83ad63cfeb diff: do not use configuration magic at the core-level
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.

Joachim B Haga 12f6c308d5 Make zlib compression level configurable, and change default.
With the change in default, "git add ." on kernel dir is about
twice as fast as before, with only minimal (0.5%) change in
object size. The speed difference is even more noticeable
when committing large files, which is now up to 8 times faster.

The configurability is through setting core.compression = [-1..9]
which maps to the zlib constants; -1 is the default, 0 is no
compression, and 1..9 are various speed/size tradeoffs, 9
being slowest.

 - Use "---\n" only where it matters -- that is, use it

   commit log and something else before the patch text.

 - Do not output spurious extra "\n"; have an extra newline
   after the commit log text always when we have diff output and
   we are not doing oneline.

 - When running a pickaxe you need to go recursive.

This lets you use something like this in your $GIT_DIR/config
file.

	[diff]
		color = auto

	[diff.color]
		new = blue
		old = yellow
		frag = reverse

When diff.color is set to "auto", colored diff is enabled when
the standard output is the terminal.  Other choices are "always",
and "never".  Usual boolean true/false can also be used.

The colormap entries can specify colors for the following slots:

	plain	- lines that appear in both old and new file (context)
	meta	- diff --git header and extended git diff headers
	frag	- @@ -n,m +l,k @@ lines (hunk header)
	old	- lines deleted from old file
	new	- lines added to new file

The following color names can be used:

	normal, bold, dim, l, blink, reverse, reset,
	black, red, green, yellow, blue, magenta, cyan,
	white

Linus Torvalds 50f575fc98 Tweak diff colors
This patch does:

 - always reset the color _before_ printing out the newline.

   This is actually important. You (and Johannes) didn't see it, because
   it only matters if you set the background, but if you don't do this,
   you get some random and funky behaviour if you pick a color with a
   non-default background (which still potentially has problems with tabs
   etc, but less so).

 - allow people to have a different color for the "file headers"
   (DIFF_METAINFO) and for the "fragment header" (DIFF_FRAGINFO). Also,
   make a difference between "normal color" and "reset colors"

 - default to red/green for old/new lines. That's the norm, I'd think.

 - instead of that eye-popping (and eye-ball-with-a-fondue-fork-popping)
   purple color for metadata, use bold-face for file headers, and cyan for
   the frag headers. I actually prefer the "gray background" for that, but
   it only works well in xterms, so COLOR_CYAN it is..

We used to parse "-U" and "--unified" as part of the GIT_DIFF_OPTS
environment variable, but strangely enough we would _not_ parse them as
part of the normal diff command line (where we only accepted "-u").

This adds parsing of -U and --unified, both with an optional numeric
argument. So now you can just say

	git diff --unified=5

to get a unified diff with a five-line context, instead of having to do
something silly like

	GIT_DIFF_OPTS="--unified=5" git diff -u

(that silly format does continue to still work, of course).

Linus Torvalds 5d6a9f45e1 Fix "git diff --stat" with long filenames
When we cut off the front of a filename to make it fit on the line, we add
a "..." in front. However, the way the "git diff" code was written, we
will never reset the prefix back to the empty string, so every single
filename afterwards will have the "..." prefix, whether appropriate or
not.

You can see this with "git diff v2.6.16.." on the current kernel tree,
since there are filenames with long names that changed there:

 [ snip snip ]
 Documentation/filesystems/vfs.txt                  |  229
 .../firmware_class/firmware_sample_driver.c        |    3
 .../firmware_sample_firmware_class.c               |    1
 ...Documentation/fujitsu/frv/kernel-ABI.txt           |  192
 ...Documentation/hwmon/w83627hf                       |    4
 [ snip snip ]

notice how the two Documentation/firmware** filenames caused the "..." to
be added, but then the later filenames don't want it, and it also screws
up the alignment of the line numbering afterwards.

Trivially fixed by moving the declaration (and initial setting) of the
"prefix" variable into the for-loop where it is used.

Junio C Hamano 0660626caf binary diff: further updates.
This updates the user interface and generated diff data format.

 * "diff --binary" is used to signal that we want an e-mailable
   binary patch.  It implies --full-index and -p.

 * "apply --allow-binary-replacement" acquired a short synonym
   "apply --binary".

 * After the "GIT binary patch\n" header line there is a token
   to record which binary patch mechanism was used, so that we
   can extend it later.  Currently there are two mechanisms
   defined: "literal" and "delta".  The former records the
   deflated postimage and the latter records the deflated delta
   from the preimage to postimage.

   For purely implementation convenience, I added the deflated
   length after these "literal/delta" tokens (otherwise the
   decoding side needs to guess and reallocate the buffer while
   inflating).  Improvement patches are very welcomed.
