(Haven't looked at your patch.)

Sounds like a reasonable, and useful thing to do.

However, `comment-region' also has optional behaviors
that involve its use of a prefix arg.  How with those
interact with what you propose?  Do they even make
sense (e.g. nesting comment levels and unnesting them)?

My guess is that what's needed is a separate command.

I'm guessing completely different prefix-arg behavior
would be appropriate for multi-line comments.  Maybe
you can find a way to merge the two without confusing
users (and the doc).  Or maybe it's not worth trying
to do that, and a separate command makes more sense.
Dunno.
