PJE already said that intent is that PEP will only have Python 3
compatible code in it. Not attempting to have examples that work for
both Python 2 and Python 3.

That sounds to me then that we should be using what 2to3 changed it to. Ie.,

                  if headers_sent:
                    # Re-raise original exception if headers sent
                    raise exc_info[0](exc_info[1]).with_traceback(exc_info[2])
