Downgrade the input filtering from a showstopper. No one seems interested

in discussing OtherBill and my points at this time, so it can't be a bug
in anyone's rear end.  As stated, the code works for the most part.

And, if we did do another round of filter changes, I'm inclined to see it
happen in 2.1.
