This would be somewhat tricky, because our COMMENT support assumes
that the object upon which we're commenting has an ObjectAddress, and
individual arguments to a function don't, although perhaps the
sub-object-id stuff that we currently use to handle comments on table
columns could be extended to handle this case.  I guess I wouldn't
object to a well-done patch that made this work, but creating such a
patch seems likely to be tricky, owing to the fact that there's
nothing in the system that thinks of the individual arguments to a
function as separate objects at present.
