SYSCF WIZARDS

Preformat SYSCF entry 'WIZARDS' so that it can be displayed during panic
feedback without allocating memory for the formatted list at that time.
It also gets displayed for help's "support information" ('?k').

For panic(), push "it may be possible to rebuild" to a second line since
the formatted usernames might make the line long.
