Yeah, that was kind of what I felt about it. If this patch were part of
a grand plan to make IS DISTINCT FROM smarter, that would be one thing.
But if we were to embark on that, likely as not it would involve a
redesign that would invalidate this code anyway. So I'd just as soon
keep it simple for now.
