I found this issue after helping someone solve a Stack Overflow question at https://stackoverflow.com/q/58767241/100297; they eventually figured out that their prefix was a path, not a path element.

I'd be all in favour of making tempfile._sanitize_params either reject a prefix or suffix with `os.sep` or `os.altsep` characters, or just take the last element of os.path.split().
