Johannes Schindelin d516c2d119 Teach git-diff-files the new option --no-index
With this flag and given two paths, git-diff-files behaves as a GNU diff
lookalike (plus the git goodies like --check, colour, etc.).  This flag
is also available in git-diff.  It also works outside of a git repository.

In addition, if git-diff{,-files} is called without revision or stage
parameter, and with exactly two paths at least one of which is not tracked,
the default is --no-index.

So, you can now say

	git diff /etc/inittab /etc/fstab

and it actually works!

This also unifies the duplicated argument parsing between cmd_diff_files()
and builtin_diff_files().

NAME
----
git-diff-files - Compares files in the working tree and the index
SYNOPSIS
--------
'git-diff-files' [-q] [-0|-1|-2|-3|-c|--cc|-n|--no-index] [<common diff options>] [<path>...]
DESCRIPTION
-----------
Compares the files in the working tree and the index. When paths
are specified, compares only those named paths. Otherwise all
entries in the index are compared. The output format is the
same as "git-diff-index" and "git-diff-tree".
OPTIONS
-------
include::diff-options.txt[]
-1 -2 -3 or --base --ours --theirs, and -0::
Diff against the "base" version, "our branch" or "their
branch" respectively. With these options, diffs for
merged entries are not shown.
+
The default is to diff against our branch (-2) and the
cleanly resolved paths. The option -0 can be given to
omit diff output for unmerged entries and just show "Unmerged".
-c,--cc::
This compares stage 2 (our branch), stage 3 (their
branch) and the working tree file and outputs a combined
diff, similar to the way 'diff-tree' shows a merge
commit with these flags.
\-n,\--no-index::
Compare the two given files / directories.
-q::
Remain silent even on nonexistent files
