LISP 104 HAS TWO NEW FEATURES, DESCRIBED
BELOW, IN ADDITION TO CORRECTIONS FOR LONG 
LOST BUGS IN THE UUO HANDLER.

  APPLY HAS BEEN GENERALIZED TO WORK
FOR FSUBRS AND FEXPRS - (APPLY F L)
WILL DO THE SAME THING AS (EVAL (CONS F L))
IF F IS AN F-TYPE FUNCTION, AND WILL OPERATE
AS NORMAL IF F IS NOT F-TY
PE.
  SUBLIS AS DESCRIBED ON P.12 OF THE LISP 1.5
MANUAL HAS BEEN IMPLEMENTED.  IT COPYS ONLY
AS MUCH OF THE SUBSTITUTED-INTO S-EXPRESSION
AS IS NECESSARY TO PERFORM THE SUBSTITUTIONS.
IT ALSO UTILIZES A FEW TRICKS TO KEEP RUNNING
TIME VERY LOW.  IF WHAT ONE IS SUBSTITUTING
FOR IS AN ATOM, THEN SUBLIS IS PROBABLY A
BETTER FUNCTION TO USE THAN SUBST.  HOWEVER,
(SUBST NIL NIL L) IS STILL THE ONLY FAST WAY
TO COMPLETELY COPY THE S-EXPRESSION L.
