This flag will show playbook output from non-failing commands. -v is also added to /usr/bin/ansible, but not yet used. I also gutted some internals code dealing with 'invocations' which allowed the callback to know what module invoked it. This is not something 0.5 does or needed, so callbacks have been simplified.
