"Assume" nothin'!  Every system I've used documents "cl" as

	Clear screen and home cursor

But it would be a reasonable thing to assume anyway, because many terminals
can't clear the screen without homing.  You can go ahead and add your extra
Goto(), but at low baud rate it can be quite noticable.  I prefer to think
that "cl" entries that don't home are busted.
