Perhaps, if you submit a patch at Sourceforge. If you don't, it won't.


I've changed the xover method to support this, feel free to change this in your
Python source tree, create a patch and submit it:

#############
    def xover(self,start,end):
        """Process an XOVER command (optional server extension) Arguments:
        - start: start of range
        - end: end of range
        Returns:
        - resp: server response if successful
        - list: list of (art-nr, subject, poster, date,
                         id, references, size, lines, xref)"""

        resp, lines = self.longcmd('XOVER ' + start + '-' + end)
        xover_lines = []
        for line in lines:
            elem = line.split("\t")
	    xref = None
	    if len(elem) >= 8 and elem[8].startswith('Xref:'):
		xref = elem[8]
            try:
                xover_lines.append((elem[0],
                                    elem[1],
                                    elem[2],
                                    elem[3],
                                    elem[4],
                                    elem[5].split(),
                                    elem[6],
                                    elem[7],
				    xref))
            except IndexError:
                raise NNTPDataError(line)
        return resp,xover_lines
#############

>2) What is the best way to get this line now?

See the above code :-)
