[issue21508] C API PyArg_ParseTuple doc is innacurate

[Josh Rosenberg]

Josh Rosenberg added the comment:

You'd prefer it say it returns 1 on success and 0 on failure? Or non-zero on success, zero on failure?

Is true/false that bad? After all, C says 0 is false, all other integer values are true; phrasing it as zero vs. non-zero may be slightly more technically accurate, but it's also a bit less readable, while 1 vs. 0 constrains the implementation (so you couldn't introduce a third "success but with additional info" state, similar to the third possible return from a "O&" converter function).
