Unnecessary message when turning off the broken lantern in the dark

[eriktorbjorn]

>LOOK
It's too dark to see.

>TURN ON LANTERN
Click. The lantern doesn't respond.

>TURN OFF LANTERN
You turn off the lantern's switch.

It's completely dark.

That's because TURN-OFF-LAMP calls KILL-LAMP, which calls SAY-IF-HERE-LIT even if the room was already dark. I could be wrong, but I think TURN-OFF-LAMP doesn't even need to call KILL-LAMP when the lamp is broken? (The simplest way to break the lamp is to kick it.)
