ZILF warning (harmless) in SPOT-F

[eriktorbjorn]

This code appears in SPOT-F:

		<COND (<HERE? IN-SHACK>
		       <TELL D ,SHACK>)
		      (TY
		       <TELL D ,TOWER>)>

ZILF warns that TY is always true. I can't see how this could be anything else than T which, of course, is also always true, but ZILF won't complain about that.
