Sorry if this question is trivial, but I searched the web and also visited the osc man page, but could not find anything.

Is there any equivalent to "git commit --amend" in osc?

As a starter, I often make small mistakes in my commits and require a couple of steps to solve them. So I end up with multiple commits that really should be one. Any way to do it (either at commit time or later on, like "git rebase -i").

Any advise is appreciated.
