Solve the following python programming problem given the following code:
@ contextmanager 
def assert_git_status_unchanged(repository) : 
    '
    Make sure that the working directory remains in the same rough state.

    :param string repository: Git repo
    ' 
    def long_status(repository) : 
        output = Repo (repository).git.status ('--long') 
        return output.splitlines () [1 :] 
before = long_status (repository) 
    (yield) 
    after = long_status (after) 
    assert (before == after), 'Working directory status has changed' 

    
    

    Fix the buggy line: after = long_status (after)
