Typo.

Looks much better.

I wondered briefly why nonfastforward was even there, as I recall that I
was the one who added it many years ago. It turns out that it used to
serve the purpose of the new forced_update, but Chris's series from a
few months ago split it out to "nonfastforward" and "not_forwardable",
and then added "requires_force" to give a single flag that is set in
either case.

So I think your simplification is correct; the first two can be local
variables, and the only thing that matters to carry forward is
requires_force (and I agree that forced_update is a better name).
