[PATCH] git send-email: allow any rev-list option as an argument.

  One can consider to squash that on top of
  <1225450632-7230-3-git-send-email-madcoder@debian.org> to be able to pass
  all non path arguments before a possible '--' to git format-patch.

  The downside of this patch is that:

    git send-email -C -C -M origin/next

  will send the content of origin/next if it's an existing file. Of course a
  disambiguation can be:

    git send-email -C -C -M refs/heads/origin/next

  But again if this file also exists, one is basically screwed. I see no
  proper way to fix that, unless to change git-send-email behaviour at once.


  Though I believe this semantics to be better than the one in the previous
  patch, as it's often a good idea to pass -M -C -C to format-patch, which is
  currently impossible. It also allow revision lists to work as expected (wrt
  --all, --not and so on).

  Comments are welcomed.
