Ah, I didn't think of it myself, but now you put it in these words,
I do agree that the view makes sense. When we have nothing of our
own, a degenerated form of a rebase is a fast-forward, even more so
than a fast-forward being a degenerated form of a merge.

Me neither. Let's not waste too much brain-cycles over this.
Thanks.
