[1] EVALHOOK NEVER SEES THE ARRAY REFERENCE OF A STORE

[A] THE DEFAULT ##MORE## PROCESSOR NOW DOES (NOINTERRUPT NIL)
[B] CHANGES TO ALLFILES:
	[B1] NAMESTRINGS ARE NOW ILLEGAL - USE NAMELISTS OR FILES
	[B2] NEW OPTIONS: BITS, CHARACTERS, BYTES, BYTESIZE
----------------------------------------------------------------
[1] TO PREVENT A PECULIAR SCREW INVOLVING THE PARTICULARLY KLUDGY
    IMPLEMENTATION OF STORE, THE EVALHOOK FUNCTION (IF ANY) WILL
    NEVER SEE THE ARRAY REFERENCE ITSELF AS A HOOKED FORM.  INSTEAD,
    IT WILL SEE ONLY SUBFORMS OF THE ARRAY REFERENCE.

[A] MY FACE IS RED.  TIME AND AGAIN I HAVE WARNED THAT ASYNCHRONOUS
    INTERRUPTS ARE ALWAYS RUN BY THE SYSTEM IN (NOINTERRUPT T) MODE
    TO PREVENT TIMING BUGS.  IT IS UP TO THE INTERRUPT FUNCTION TO
    RE-ENABLE INTERRUPTS BY SAYING (NOINTERRUPT NIL) IF DESIRED.
    THE SYSTEM-SUPPLIED ##MORE## PROCESSOR NOW DOES (NOINTERRUPT NIL)
    SO THAT IF YOU TYPE ^G (QUIT) OR ANY OTHER INTERRUPT CHARACTER AT
    IT THE INTERRUPT WILL GO THROUGH IMMEDIATELY.

[B] CHANGES TO THE ALLFILES PACKAGE, WHICH INCLUDES THE FUNCTIONS
    ALLFILES, MAPALLFILES, DIRECTORY, AND MAPDIRECTORY:
	[B1] TO PREVENT A REOCCURRENCE OF THE RECENT DISASTER IN
	     WHICH SOMEONE DID
		(MAPALLFILES 'DELETEF '((DSK LOSER) * *))
	     AND DELETED 1/3 OF ALL OF MC'S FILES BEFORE IT WAS STOPPED,
	     ALLFILES AND RELATED FUNCTIONS WILL NOT ACCEPT NAMESTRINGS
	     ANY MORE.  (RRECALL THAT THE FILESPEC ARGUMENT IS A
	     LIST OF FILESPECS; THE TRAP IS THAT ERRONEOUSLY FEEDING
	     IT A SINGLE NAMELIST WILL MAKE IT THINK IT IS GETTING A
	     LIST OF NAMESTRINGS.)  NAMELISTS AND FILE OBJECTS ARE STILL
	     ACCEPTABLE.  IF YOU REALLY WANT TO ALLOW NAMESTRINGS, YOU
	     CAN ALWAYS SAY
		(ALLFILES (MAPCAR 'NAMELIST FOO) ...)
	     AND BE VERY, VERY, VERY, VERY, VERY, VERY CAREFUL!
	[B2] NEW OPTIONS ACCEPTED BY THE DIRECTORY AND MAPDIRECTORY FUNCTIONS:
		BITS		THE NUMBER OF BITS IN THE FILE
		BYTES		THE NUMBER OF BYTES IN THE FILE
		BYTESIZE	THE SIZE OF THE BYTES
		CHARACTERS	THE NUMBER OF CHARACTERS IN THE FILE
				(THIS IS AN OLD OPTION, BUT NOW IT
				YIELDS THE CORRECT CHARACTER COUNT RATHER
				THAN ROUNDING UP TO A MULTIPLE OF FIVE)
