Yes -- as I've noted elsewhere in this discussion, Lib/unittest.py
actually contains a (minor) bug because it uses and/or where it
doesn't fit.  The code is on lines 618-619:

        self.stream.writeln("Ran %d test%s in %.3fs" %
                            (run, run == 1 and "" or "s", timeTaken))
