[issue8949] PyArg_Parse*(): "z" should not accept bytes

[Marc-Andre Lemburg]

Marc-Andre Lemburg <mal at egenix.com> added the comment:

"z" should not accept bytes... why not ?

"z" is the same as "s" with the addition that passing None
as parameter will result in the pointer to get set to NULL.

"s" accepts bytes via the buffer interface, so why should
"z" behave differently ?

If a function should only accept Unicode or None, then "Z"
should be used instead.
