The PyList_GetItem function is documented at

http://docs.python.org/api/listObjects.html

as returning "...the object at position pos...".
However, even though in python -1 is a valid index,
this function expects a 'real' index.

1) I believe it would be worthwhile pointing out in
   the API docs that in fact a positive value is
   expected.

2) It would be good to change the function signature
   to expect an unsigned int instead of an int for
   the index.

I agree with these suggestions. It's not impossible for
someone to 'just assume' a negative index is handled
correctly by PyList_GetItem().
