The 'l'ook command can reveal that doors have been opened/closed, items have been dropped/picked up, etc. outside of LOS.
'l'ooking at webs, items or doors outside of LOS can reveal their new status if a monster was wandering by.
Problem
The 'l'ook command detects webs (that have been created or no longer exist), "dedetects" items that are no longer on a tile, and shows the actual status of doors opened/closed outside LOS, if that part of the level has already been explored. This can leads to things like:
Code:
An open door.

How to reproduce it
Drop some items, and create some webs nearby with the wand or spell. Lock yourself in a room and wait until you hear ripping sounds. Now 'l'ook at the tiles where the webs are on and the game will say "A section of floor." even if there's a | on your cursor. The items you dropped have probably been picked up, and the same will happen then.
