Summary: Py_INCREF(Py_None) in documentation

Initial Comment:
Since 5 hours I am debugging the pygsl (
http://pygsl.sourceforge.net ) module... The reason: I
forgot to increment the reference counter of Py_None
before returning it. Maybe it is a good idea to
underline this case. The Py_None object is a constant
pointer, maybe some other people do not think about it.

Here is a code example:

static PyObject* my_func(PyObject *self,
                           PyObject *args
                           )
{
  Py_INCREF(Py_None);
  return Py_None;
}

Is it possible, that this case was handled without
reference counter in version 2.0 and older?
