Hi there,

I just lost quite some work, because `git stash; git stash pop` doesn’t seem to understand the concept of the index correctly.

To reproduce:

dwt@crest ~/Desktop % cd test

On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

	modified:   foo

no changes added to commit (use "git add" and/or "git commit -a")

What git stash does get right is that it does remove everything that is stashed from the current state of the repo, but what it doesn’t get right is restoring that state fatefully in `git stash pop`.

As a user, I would expect that `git stash pop` undoes the change that `git stash` inflicted.
