Fix:	SE035

Problem:
	Crashes with a segmentation fault in player selection menu of tty
	interface. This is because the longer menu in Slash'EM overlays
	the status line and botl() is called to refresh this when the
	menu is closed. I'm not clear why the same problem did not occur
	in 0.0.5E7, but I've fixed it my checking in botl() to see if
	this applies and returning without doing any work if it does.

Compatible with:
	Slash'EM 0.0.5E9 (DOS only)
