[PATCH 2/2] diff: Remove -q to stay silent on missing files.

[Stefan Beller <stefanbeller@googlemail.com>]

This feature was not tested in the test suite, hence we'd remove it for
now. It doesn't seem to be often used anyway.
A google search for "git diff -q" (match string exactly) only returned
http://stackoverflow.com/questions/11021287/git-detect-if-there-are-untracked-files-quickly
where "git diff -q" was quoted for its exit code behavior regarding files
being found or not.
