[ itch... ] That code is just completely wrong, because the contents
of a TEXT datum aren't guaranteed null-terminated. It'd be better to
invoke bttextcmp and negate its result.
That's not relevant to your immediate problem, but if you've noticed
any strange behavior with your text_revop indexes, that's the reason...
