Nonetheless, it had bugs crawling out of it everywhere ... try more
complex test cases, and pay attention to whether you actually get
the right answer (like the right sort order, distinct/not distinct,
etc).  Cross-datatype cases tended to coredump, too.

I believe this mess is all fixed as of 7.1.
