What I'm doing for this is that when I apply the patch I save a
git note with the message ID and various other things then when I
push the patch out and generate the "applied, thanks" e-mail I
look for the git note and use that.  My script can also fall back
to patchwork for the lookup but it's not 100% reliable and
greatly increases the network access needs.
