Back out the behavior change to magic words outside the Giant's Room.

There are twi reasons for this. One is to decompolicate verifying
the fix for issue $85: revisiting "fee fie foe foo" and "fum". The
other is because I'm now convinced that the test should notr be
"Are you in the Giant's Room" but :Have you read the grafitti there?
