Message 92492 - Python tracker

it seems to me, that any and all readline interfaces should/could
standardize to the indexing scheme as used by the language; maybe i'm
wrong, but since python is zero based, so could the readline interfaces.

it's definitely more logical for a python programmer to expect
zero-based, and the code will match with the python code.

i would propose that everything be zero-based;
this is duplicate/similar of/to http://bugs.python.org/issue6786
