This turned out to be quite easy. git-merge-resolve handles the tree-ish
argument just fine. But it's possible other merge helpers might not be
so happy. I dunno.

  [1/3]: cherry-pick: handle root commits with external strategies
  [2/3]: revert: allow reverting a root commit
  [3/3]: t3503: test cherry picking and reverting root commits
