That's the exception which proves the rule.  Prof. Wirth added a couple of
IOs while he was experimenting with programming PIC chips for a project
(see his section on PICL), and I persuaded him to make it an 8-bit GPIO
port.  So my bad!  :)  Consider it experimental.  All the rest is
documented, right?
