Yup.  Because the supporting PyString_FromFormatV() doesn't know
anything about z qualifiers now, if you _tried_ to use %zd then even
on a C99-platform PyString_FromFormatV() wouldn't do any conversions
from that point on:  it would just copy the format string from the
first "z" onward into the output buffer, and ignore the trailing
inputs.  The good news is that we could teach it about "z" (but would
still need a macro or some such to implement "z" correctly across
platforms).
