[RFC PATCH 0/3] Send more rebases through interactive machinery

This series:

  * deletes git-rebase--merge, making git-rebase--interactive handle
    those cases instead
  * adds an --am option to git rebase, and changes the rebase default
    from using git-rebase--am to git-rebase--interactive, fixing
    directory rename detection for default rebases.

However:

  * this series has several minor conflicts with ag/rebase-p in pu.
    But it's just an RFC for now; I can re-roll on top of that after
    getting some feedback.

  * this series depends on the other preparatory fixups under
      https://public-inbox.org/git/CABPp-BGxaroePB6aKWAkZeADLB7VE3y1CPy2RyNwpn=+C01g3A@mail.gmail.com/
    To get this series with the preparatory fixups:

Fetch-It-Via: git fetch https://github.com/newren/git rebase-new-default

Elijah Newren (3):
  git-rebase, sequencer: add a --quiet option for the interactive
    machinery
  rebase: Implement --merge via git-rebase--interactive

Yes, there are a significant number of testcase changes below. See the relevant commit messages where I explain why each was changed.
