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. Signed-off-by: Raphael Zimmerer <killekulla@rdrz.de> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
