Code Issues Proposed changes
keystonemiddleware/keystonemiddleware/tests/unit/auth_token/test_auth_token_middleware.py
Jamie Lennox 7074ee23b5 Remove the _msg_format function 
The _msg_format plugin was just a way to print out the debug statement
from environment variables. We can do this directly from the user plugin
rather than using env.
