Which exception would you expect? ValueError? Another error?
I used the same exception for addch(int) and addch(str). addch(int)
already raises an OverflowError on Python 3.2 if the value doesn't fit
in a C long type (which may be bigger than chtype, Python 3.3 is more
strict), so applications don't need to be changed for the "new" error
