1. a pre-condition assumes that there is always a stash on the stack when git stash branch is called,
which is not necessarily true

2. the cleanup code assumes the specified stash is a stash reference, rather than an arbitrary commit.

The tests test_expect_failure tests in this patch demonstrate these issues.
