[Python-Dev] Support byte string API of Windows in Python3?

["Martin v. Löwis"]

I see. I'd like to know whether that's an incompatible change. We
shouldn't make incompatible changes in that matter. However, if you were
not able to pass a bytes cwd on Windows before, it's fine that you still
are not able to.

I'm puzzled how your patch could have possibly affected Windows, since
it was only change _posixsubprocess.c. So I'm closing the report again.

Ok, I'll close this as well.
