The following commands have been removed and are now changed using the "change"
command (as of the next reboot):

  autoexits
  brief
  compact
  incognito
  nobeep     (change beep)
  prompt
  spam

As some clients may call some of these commands, they may stop functioning
correctly. To work around it, define aliases:

  > alias brief change brief
  > alias prompt change prompt
  > alias spam change spam
