appropriate. It also removes some obsolete, unused code to check the number of users on the system (obsoleted by dm); removes a prototype for an unused function that was removed earlier; and removes a control character from one message that was I think intended to clear the screen on some particular terminal (though I can't find the comment to that effect in any of the BSD source trees I have handy) but no longer serves any useful purpose. From PR 6580 by Joseph Myers <jsm28@cam.ac.uk>. Also contains two more patches, one in teachgammon/tutor.h (by Joseph) and one in common_source/fancy.c (by me).
