The test looks good, but without the changes in patch 5 it fails and so 
adding it here breaks running "git bisect" on this series. I'd squash 
this into the final patch and I think we can probably replace an 
existing "stash apply --index" tests that are not so strict with this 
one, rather than adding a new test.

Thanks
