The easiest workaround would be setting GIT_EDITOR=true, which matches
the recommendation in [1].

Short of that, you can't do a non-interactive rebase, since we rely on
the todo list generated by interactive rebases in order for
`--autosquash` to work.

Presumably plumbing in a new `--[no-]edit` option would be fairly
straightforward, and once that is done, the change boils down to just:
