Just to be clear I didn't mean to modify --fixup behavior. It could be
--amend-old-commit or something like that. It's actually --amend that
made me want to put the UI in "git commit". But it's a bad idea
(besides what you pointed out) because after you're done, you still
need to do "git rebase --continue".

Sounds good.

This is not interactive (except when merge conflicts occur), is it?

A bit off topic. I sometimes want to fix up a commit and make it stop
there for me to test it again but there is no such command, is there?
Maybe we could add support for "fixup/edit" (or "fe" for short) and
"squash/edit" ("se"). Not really familiar with the code base to do
that myself quickly though.

Yes! Done this sometimes (not so often) but a definitely nice thing to
have. I'd go with --remove or --delete though.
