Why is verifying such tests "the wrong thing"? It's a while ago that I
wrote the tests, but IIRC I've added them exactly because I did expect
that such tests should pass, and they didn't. I even fixed some trivial
corner cases when writing the tests. as far as I understood the code.

Best regards, Michael.
