git grep: Add "-z/--null" option as in GNU's grep.

Browse Source 
Here's a trivial patch that adds "-z" and "--null" options to "git
grep". It was discussed on the mailing-list that git's "-z"
convention should be used instead of GNU grep's "-Z".
So things like 'git grep -l -z "$FOO" | xargs -0 sed -i "s/$FOO/$BOO/"'
do work now.
