Lost files after git stash && git stash pop

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue) ``` git init mkdir README touch README/README git add . git commit -m "Init project" echo "Test" > README/README mv README/README README2 rmdir README mv README2 README git stash git stash pop ```

What did you expect to happen? (Expected behavior) I expected that after the `git stash pop` the README file would be back.

What happened instead? (Actual behavior) This README with "Test" file was deleted and I lost 5 hours of work.

What's different between what you expected and what actually happened? The file doesn't exist anymore and I can't recover it.

Anything else you want to add: This is just a reproducible example.
