Add an inscription for not picking up an item

[Leszczynek]

...that could be used for unidentified items. If I'm sure or almost sure a certain type of potions is degeneration (I either identified all other common potions or I found it in a vault where I know there's degeneration), I don't want to either waste a scroll of identify or pick it up anymore, but I can't exclude it from autopickup until I identify it. I can only exclude all unknown potions.

So please an inscription like maybe !g to automatically not pick up the inscribed type of item, especially since the reverse inscription, =g, already exists.

Usage:
- unidentified potions of degeneration
- thrown ammo/needle brands you don't care about on a particular character but don't want to exclude completely from your .rc file

or I found it in a vault where I know there's degeneration

I'd say such vaults just shouldn't exist. It's pure spoileriness with no redeeming quality. Vaults that are guaranteed (or even just more likely) to have a specific unidentified item shouldn't exist. If an item in a vault is guaranteed to have a certain property (specific potion or scroll, or weapon or armor with a specific ego), it should generate identified.
