[issue17702] os.environ converts key type from string to bytes in KeyError exception

[R. David Murray]

R. David Murray added the comment:

with self.assertRaises(KeyError) as cm:
    os.environ[missing]
self.assertEqual(cm.excecption.args[0], missing)

(I don't know why assertRaises returns itself rather than just returning the 
exception in the with, but that's the API).
