#M32: Astral vision vs normal vision

While wearing EotO, ";" and selecting a monster behind a wall would display
"normal vision" as well as "astral vision".  This is because cansee() gets
set for things seen via astral vision.  However, couldsee() is only set for
things that could be seen normally, so check both values.
