This patch is very similar to #1520081. They both suggest replacing set_option_negotiation_callback with a method on the Telnet object which I think makes perfect sense. They both contain big and useful updates to the documentation. This patch also contain a useful refactoring of the process_rawq() method. I think a merged patch of them both should be applied. But IMHO, it should wait to Py3k because then API can be broken and then set_option_negotiation_callback can be eliminated.
