    Why WHY WHY was STRING-MISMATCHQ changed?  It was working so well....
    STRING-MISMATCHQ should return a FIXNUM (index of first change)
    or it should return NIL (no difference in strings). 
    .  .  .
STRING-MISMATCHQ now works ok in version 153 (now on LISP;).  Soley, this 
problem and the recent string gc probelm are partly to blame on you and your 
idea of having a STR/:COMPARE-WORDS -- had it been left to me, there would
have been no desire to fiddle with tenuously-working code.  No more "ideas" 
for STRING.
