Apparently docutils.io.FileOutput.close() closes sys.stdout:
    def close(self):
        self.destination.close()
        self.opened = False

self.destination == sys.stdout

Yesterday. Previously rst2html.py with Python 3 was failing with AttributeError in
docutils.core.Publisher.process_command_line().

The output with Python 3.1 is identical as with Python 3.2.

Yes.
