Current master post-4.2.1

[PowerWyrm]

Ok a funny bug I discovered while playing my variant that I managed to reproduce in current V. Here's how to reproduce it:
- get two stacks of identical items in the inventory (this is very easy to attain with scrolls of Phase Door): for example, a) 40 scrolls of Phase Door and b) 10 scrolls of Phase Door
- read one scroll from pile a)
- result: message "You have 39 scrolls of phase door (a)" but when you look at your inventory, you have in fact a) 40 scrolls of Phase Door and b) 9 scrolls of Phase Door
- repeating the operation depletes stack b) even if you read from stack a)

I suppose it's because pack is reordered so the 39+10 scrolls become 40+9, but it feels like you read from wrong pile.
