Wrapping python doctest results that are longer than 80 characters

Just figured out:

def long_string():
    """
    Returns a string which is wider than the recommended PEP8 linewidth

    >>> print long_string()
    01234567890123456789012345678901234567890123456789012345678901234567890\
12345678901234567890123456789

    """
    return '0123456789' * 10

Hope that helps somebody else out.
