From a bug report, eating Medusa's corpse is fatal
but devouring her whole (purple worm or poly'd hero) was not. Now it will
be. Also, being killed by swallowing a cockatrice or a Rider could have
disclosed "you went without food" if you hadn't eaten anything else prior.
This fixes that too, although it might be a little silly if it happens to
a monk since he'll feel guilty (for non-vegetarian diet) right as he dies.
