My patch on the tracker already implements %a, it's simple. Just
call PyObject_ASCII() (same as ascii()) then call
PyUnicode_AsLatin1String(s) to convert it to bytes and stick it in.
PyObject_ASCII does not return non-ASCII characters, no decode error
is possible. We could call _PyUnicode_AsASCIIString(s, "strict")
instead if we are afraid for non-ASCII bytes coming out of
