Unclear when staff of levitation runs out.
I used an uncursed staff of levitation, and now the status bar displays 'Levitating'. I walked back and forth over a pit trap for about 20 turns without getting a message.
However, when I started getting "you barely avoid a pit trap!" messages again, my status bar still reads 'Levitating'.
It would be good if the effect sends a message to the buffer and clears the status bar when the effect runs out.
