[issue15180] Cryptic traceback from os.path.join when mixing str & bytes

This is definitely a motivated change ;-). I would like this re-typed as behavior and applied to 2.7, 3.2, and 3.3. I see the current message as being much like a garbled sentence in the docs that people can only understand if they already understand the background.
