Summary: _Subfile.readline( ) in mailbox.py ignoring self.stop

Initial Comment:
I'm using Python 2.3.3 (on Windows, but that shouldn't 
matter) and I've noticed a problem with the internal 
_Subfile class in mailbox.py.  The readline method 
doesn't consider self.stop if the length argument is not 
None.  It has:
    if length is None:
        length = self.stop - self.pos
when really it should have something like:
    if length is None or length < 0:
        length = remaining
    elif length > remaining:
        length = remaining
which is what the read method does.

This is correct. After fixing this bug the read() and
readline() methods are identical, except for one function
call, so my patch refactors their bodies into an internal
_read() method.
