An error was reported on The following code in a Python 3
extension module generated an error:

If I use the following C code

static PyObject* foo(PyObject *self, PyObject *args, PyObject *kwrds)
  char a, b;
  char *kwlist[] = {"a", "b", NULL};
  if (!PyArg_ParseTupleAndKeywords(args, kwrds, "|CC", kwlist, &a,
    return NULL;

then the following works:

>>> foo('a')
>>> foo('a','b')
>>> foo(a='a',b='b')

but the following fails:
>>> foo(b='b')

RuntimeError: impossible<bad format char>: 'CC'


I traced it down to missing case statement for "C" in skipitem() in
getargs.c. The attached patch seems to fix the issue.
