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().
