From a bug report, feedback of the form
Status of the fog cloud (neutral): Level 2 HP 5(5) AC 0, engulfed you.
sounds odd. "Engulfing you" seems a little odd as well, since the engulf
has already taken place, but I think it works out better. For symmetry,
replace "swallowed you" by "swallowing you". But that one will never
occur, because all the animals with engulfing attacks will now yield the
more precise and much more significant "digesting you".
The code formatting is strange. Lining up the text parts works out
a lot better than attempting to fit the associated tests within the space
left after the large indentation being used.
