- Add a new command 'lsdev' to list devices which might be likely to host

   filesystems.
 - New 'help' command and data in the help.* files (not yet installed),
   provides topic and subtopic help, indexes, etc.
 - Don't crash if the user tries to set an invalid console.  Be helpful
   instead.
 - Expand tabs (badly) on the i386 video console.
 - Some minor cosmetic changes.
