Summary: doctest's ELLIPSIS and multiline statements

Initial Comment:

The doctest ELLPSIS marker (default: "...") may be
confused by the doctest parser with the multiline
statement marker ("..."). 

Example: in the following code, the intent was to accept
any result after "print 42". This is NOT a multiline
statement,
but however the test fails (Expected: nothing, Got: 42).

----------------------------------------
#!/usr/bin/env python

import doctest

def test():
    """
    >>> print 42 #doctest: +ELLIPSIS
    ...
    """

def run():
    "Run the test."
    doctest.testmod()

if __name__ == '__main__':
    run()

That's true.  doctest has few syntax requirements, but the 
inability to start an expected output block with "..." has 
always been one of them, and is independent of the 
ELLIPSIS gimmick.  I doubt this will change, in part because 
the complications needed to "do something about it" are 
probably pig ugly, in part because it's so rare a desire, and in 
part because there are easy ways to work around it (like 
arranging for the expected output to start with something 
other than '...').
