Yes, sorry for not following up on that comment.  The point is that
rebase without --interactive never fast-forwards.  So if you do not need
to edit your branch interactively, it should work for your purpose.

I like --no-ff better. :)

While at it, I should mention another documentation problem: rebase’s
man page does not explain that rebase --interactive will fast-forward at
the beginning of the series.  It should say that rebase -i will do that
and rebase without -i will not.  I can prepare a patch to fix it this
evening.

Sounds interesting.  Simpler to use "rebase (-f | -i --no-ff)", I think.
Or maybe rebase could learn a no-op --no-ff option to make it easier to
switch between it and rebase -i, and this would become
"rebase (-f | -i) --no-ff".
