Code Issues Proposed changes

add a null logging handler

Browse Source 
Python libraries that log should set a NullHandler in case the
application where they are used does not set up logging. Reno's use in
the Sphinx extension and in some release tools generates warnings the
first time logging calls are made because of the missing handler.
