[PATCH v2 0/2] rebase -i: introduce the 'break' command

Stefan asked a while back [https://public-inbox.org/git/20180118183618.39853-3-sbeller@google.com/] for a todo command in interactive rebases that would essentially perform the "stop" part of the edit command, but without the "pick" part: interrupt the interactive rebase, with exit code 0, letting the user do things and stuff and look around, with the idea of continuing the rebase later (using git rebase --continue).

This patch introduces that, based on ag/rebase-i-in-c.

Changes since v1:

 * Wrapped the commit message correctly.
 * Added a preparatory patch to mention what happens in case an exec fails.
 * Mentioned the break command in the git-rebase(1) documentation.

Johannes Schindelin (2):
  rebase -i: clarify what happens on a failed `exec`
  rebase -i: introduce the 'break' command
