Sadly, we don't currently have anything like a `fill-region-function`,
but that's "a bug, not a feature", so we should write new code such that
this misfeature is easier rather than harder to fix in the future.

Yes, I've had this in my TODO for many years.  🙁

Actually, I think I want a `fill-region-as-paragraph-semlf'.
And maybe then some way to tell the `fill.el` code to use that instead
of the default `fill-region-as-paragraph`.
