[PATCH 0/5] rebase: calculate patches in upstream correctly

I worked on these patches last year but never sent them because I wasn't sure how they impact performance. I was hoping that getting the patch body from the commit and avoiding the call to mailinfo would make am-based rebase a little faster, but if I remember correctly, it got a little slower instead (not by much, though). I was also working on a way to implement the 'git cherry' functionality in 'git rev-list', but I wasn't sure how that would work and I ran out of time. I hope at least some of these patches can still be useful.

Martin von Zweigbergk (5):
  rebase: don't source git-sh-setup twice
  rebase --root: print usage on too many args
  am --rebasing: get patch body from commit, not from mailbox
  am: don't call mailinfo if $rebasing
