Potion messages and effects

(Adapted from the WCST spoiler "spoil803".)

What happens when you (q)uaff a potion usually depends on whether the potion was blessed, uncursed, or cursed. If a monster can quaff a potion, the effects upon the monster are documented below; all other potions won't be quaffed by monsters.

When a potion hits a monster, the monster will be awoken and has an 80% chance of losing one hit point (but not killed), and then suffers the effects described below. If you didn't see the monster get hit, you will be told, "Crash!". Monsters are not angered by potions of (extra|full) healing, (gain|restore) ability, speed, invisibility, water thrown at gremlins, or unholy water thrown at werecreatures, demons or undead; other potions will cause peaceful monsters to become hostile if you were the thrower.

If a potion hits you, you lose 1 to 2 hit points and get the effects of breathing vapors described below unless the potion has a specific effect for hitting you. You may also breathe vapors if you are near a potion when it breaks (e.g., it hit a monster, was hit by a wand of striking, or was kicked). If you are polymorphed into an unbreathing monster, the vapours will get into your eyes for the same effect. If you are polymorphed into a monster that neither breaths nor has eyes, vapours will have no effect.
