SF bug http://sourceforge.net/bugs/?func=detailbug&bug_id=130242&group_id=5470
SF patch http://sourceforge.net/patch/?func=detailpatch&patch_id=103453&group_id=5470
PyMember_Set of T_CHAR always raises exception.
Unfortunately, this is a use of a C API function that Python itself never makes, so
there's no .py test I can check in to verify this stays fixed. But the fault in the
code is obvious, and Dave Cole's patch just as obviously fixes it.
