[RWK at MIT-MC (Robert W. Kerns)]

The reason why your MC:ALAN;SPLICE ING file makes ~ start losing
on '(A B . ~(C)) is because LISP is taking the CDR of the C, and
checking that against NIL.  The CDR is the PLIST, and you put something
on C's PLIST.  I'm not sure if we've got two pieces of code joining where
they shouldn't or what, but I'll investigate further.
