Thanks. As always, I find it interesting to see your workflows.

Interesting. I'd have probably done it with an interactive rebase:

  $ git rebase -i HEAD~4
  [change first "pick" to "edit"; after stopping...]
  $ git reset --hard HEAD^ ;# throw away patch 1
  $ git am -s mbox         ;# apply single patch
  $ git rebase --continue

Which is really the same thing, but "cheats" around the cherry-pick
problem by using rebase (which I think handles the rewriteref stuff
correctly even in interactive mode).

I guess if we wanted to be really fancy, just replacing the first "pick"
with "x git am -s mbox" would automate it. That might be handy for the
multi-patch case.

Anyway, thanks for handling it. :)
