[PATCH] Add git-rev-list --invert-match
Example usage:
git log --invert-match --grep="uninteresting"
This command will prune out all commits that match the grep pattern.
How it works:
The --invert-match flag sets invert_match, in rev_info. This boolean
is later checked in commit_match() and if set it inverts the result of
grep_buffer().
