Changed applicable use of char * declarations that are passed into

brettcannon · brettcannon · commit 289e4cba1cce · 2004-06-29T03:48:23.000Z
PyArg_ParseTuple() to ``const char *`` to match the recommendation made in
section 1.3 and to support better coding habits.

Section 1.8 ("Keyword Parameters for Extension Functions") and it's coding
example were not touched since it is stems from an accredited source and thus
did not want to step on anyone's toes.
