Well, other things being equal I'd have preferred to keep the
one-argument version too. But this thread has made it even clearer than
before that we will get continuing bug reports if we leave the behavior
alone. I don't think the ability to leave off the delimiter value is
worth the amount of confusion it'll cause.
