                Blank lines can be marked with <BLANKLINE>:
                    >>> print('foo\n\nbar\n')
                    foo
                    <BLANKLINE>

                If the ellipsis flag is used, then '...' can be used to
                elide substrings in the desired output:
                    >>> print(list(range(1000))) #doctest: +ELLIPSIS
                    [0, 1, 2, ..., 999]
