Important Tass patch

[Rich Skrenta]

[I sent out a bogus patch this morning.  If you've applied it, undo it
before applying this one.  Sorry]

Tass 3.2 will croak if it sees an article and can't find a From: or Subject:
line in it.  The following patch should fix this, as well as a delete/backspace
bug.
