You are trying to abuse git-stash, but it does not cooperate because it was not designed to be abused ;-) git-stash is not intended as a generic push-and-pop-my-changes work horse.
In what way is using the documented -p switch abuse?
The purpose of git-stash is that you can "move away"
Yes, and then move back. That is why it is broken that you can not immediately move back after a stash -p.
- all of your changes to have a clean worktree or - part of your changes to _create a clean worktree from the remaining changes_. That is, before you can think of applying a stash, you are expected to have cleaned out your worktree.
It is obvious that is the assumption that stash was originally made with, and it might make some sense if it always left the tree in a clean state, but it no longer makes sense given -p and how it can leave the tree in a not clean state.
This is clearly a case of the initial implementation being a bit lazy. pop already performs a type of merge, just on a whole file basis. In other words, the pop leaves you with some files from before the pop, and some files that were modified by the pop. It should do a proper merge instead of a lazy whole file merge.
