Indeed, the filling code doesn't know much about comments and often gets
it wrong.

You don't?
Instead, write your own function that will try to find the beginning/end of
the enclosing comment and then calls fill-region-as-paragraph.
I had started to work on extending fill.el so that it used syntax-tables to
correctly respect comment and string boundaries when filling, but never got
far enough to get something really usable.
