OK, it was closer to the latter.

But why is it OK to leave @{-1}, which is just as "hmm, I do not remember what the previous branch was myself" when the user says "@{-1}" in the output while it not OK to leave "-" in the output?

I do not think of any sane reason, and that is why I think this improvement is not part of "teaching rebase that '-' can be used in place of @{-1}" topic.
