Stefan asked a while back [https://public-inbox.org/git/20180118183618.39853-3-sbel...@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 v2: * Fixed two typos. * When interrupting the rebase, break now outputs a message. 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.
