From a bug report, applying a
mirror at sleeping Medusa yielded "too tired to look at your mirror" even
even though the item being used was listed in inventory as "looking glass".
Several other messages and any target monster would produce similar things.
Perhaps they should auto-ID when applied, but I changed messages to use
the description if real name isn't known.
This also treats incubi identically to succubi regarding mirrors:
they like to see their own image and will take the mirror away when one is
applied at them.
