It's a STUPID diff, where the stuff is zero'd in pv_unlink(). Sigh. Look
before you leap. Watch where you're going. Eat your vegetables. READ THE
CODE CAREFULLY!

I just must not be fully awake these days. Sorry. Hope no one else applied
that patch. Some of it will be back again, but not all.

Is there a place where GNATS documentation can be found on the web? I'd
like to figure out how to modify a previous PR (or two) instead of
submitting a new one.
