When rewriting commits on a topic branch, sometimes it is easier to compare the version of commits before and after the rewrite if they are based on the same commit that forked from the upstream. An earlier commit by Junio (fixed up by the previous commit) gives "--onto A...B" syntax to rebase command, and rebases on top of the merge base between A and B; teach the same to the interactive version, too.
