5.0 SUGGESTIONS
.PARAGRAPH
IN HELP *, ONLY LIST THOSE FILES WHICH CAN BE LOOKUP-ED

HELP SHOULD REMEMBER THE RESULTS OF THE LOOKUPS FOR SUBSEQUENT
PASSES.

THE MONITOR SET WATCH AND SET TTY COMMAND ARGUMENT LISTS SHOULD
BE LISTED BY HELP *.  THIS NEEDS THEM TO HAVE GETTAB TABLES DEFINED,
SO WILL BE POSTPONED UNTIL 5.07.
