Most hooks that are trying to do this use "$NEW_HEAD --not --all" to
only examine commits that would be newly reachable. Already reachable
commits are presumed valid. If you want to merge someone else's
commits, just make sure they have already pushed their commits to a
branch somewhere, like a refs/heads/$USER/ sandbox space or something.
