skipitem() (in Python/getargs.c) has to be taught about all the "format units" understood by PyArg_Parse. There's a note at the top of the format-unit-understanding code saying

When you add new format codes,
please don't forget poor skipitem() below.

Well, someone forgot poor skipitem() when they added 'Z'.

Since this is a bugfix, I assert it should go into 3.2, then get forward-ported into trunk. So, step 1: check the attached one-line patch to 3.2.

Georg: sound good?

[birkenfeld]

Sound good.
