There is the post-applypatch hook you can define after the patch gets applied and produces a commit.
I use it to maintain the amlog notes in my repository (iow, I do not amend the commit, but add notes to the resulting commit so that I can tell, given a commit, which message resulted in it).
If you want to amend the resulting commit instead, the place to do so would be where I call "git notes --ref amlog" in the sample script.
