stash -u deletes ignored files

["Киселёв Максим Алексеевич" <kiselevma@gmail.com>]

There seems to a bug in git stash. Subfolders with ignored files are
deleted if the subfolders themselves are not ignored.

How to reproduce.
---
mkdir TestRepo
cd TestRepo
mkdir Ignored
echo " " > Ignored/Ignored.txt
echo "Ignored/Ignored.txt" > .gitignore
echo > File1.txt
git init
git add .
git commit --message="Initial commit"
echo "Test change" > File1.txt
git stash -u
git stash pop

Expected result:
Ignored/Ignored1.txt is present in the repository. It is either not
deleted after stash or at least restored after pop.

Actual result:
Ignored is deleted along with any files in it.

I use git version 1.7.9.msysgit.0

Sebastian Schuberth could reproduce this as well:
