No, if "F" is the head of "feature", then it does _not_ have the merge. But it's not the merge that is important, it is really the fact that if we are rebasing "feature" on "master", that "master ^feature" is empty. IOW, we are already a superset. In this example, though, the merge is the thing that gives us that superset.

Ah, I see. Yes, in that case, we should definitely be fixing "git rebase -p -i".
