+1 for this version from me, as it means we have:

- os.fsencode(obj) as the coerce-to-bytes API
- os.fspath(obj) as the str/bytes hybrid API
- os.fsdecode(obj) as the coerce-to-str API
- os.fspath(pathlib.PurePath(obj)) as the error-on-bytes API

That more strongly nudges people towards "use pathlib if you want to
ensure cross-platform friendly path handling", which is an outcome I'm
fine with.

Cheers,
Nick.
