Yes, but I would do it just as a let since the setting is only needed
for the formatting operation.  Better not to have a buffer-local
override the user's global preference if you don't have to.

Not that normally there would be any subsequent filling to make a
difference, since the buffer is read-only after formatting, but just in
case.
