    Exception raise error

    Fixes bug #916827

    As per: http://docs.python.org/library/stdtypes.html
    ?highlight=__exit__#contextmanager.__exit__

    Ionut Artarisi wrote:

    The exception passed in should never be reraised explicitly - instead,
    this method should return a false value to indicate that the method completed
    successfully and does not want to suppress the raised exception.
    This allows context management code (such as contextlib.nested) to easily
    detect whether or not an __exit__() method has actually failed.
