Makes sense to me. So, -NUM would actually mean "rebase the last NUM
commits" (as well as being an alias for HEAD~NUM), but would fail when
it does not make sense (with an error message explaining the situation
and pointing the user to HEAD~N if this is what he wanted).

This would actually be a feature for me: I often want to rebase "recent
enough" history, and when my @{upstream} isn't well positionned, I
randomly type HEAD~N without remembering what N should be. When N is too
small, the rebase doesn't reach the interesting commit, and when N is
too big, it reaches a merge commit and I get a bunch of commits I'm not
allowed to edit in my todo-list. Then I have to abort the commit
manually. With -N failing on merge commits, the rebase would abort
itself automatically.
