Sphinx warnings when building documentation with current sphinx

Description

Using a current sphinx to build documentation gets a lot of these warnings:

/Users/johanna/bro/master/build/doc/sphinx_input/scripts/policy/protocols/ssh/geo-data.bro.rst:None: WARNING: 4 column based index found. It might be a bug of extensions you use: [('single', u'SSH::watched_countries', u'id-SSH::watched_countries', u'id-SSH::watched_countries')]

issue seems to be https://github.com/sphinx-doc/sphinx/issues/2673

I am not sure this is worth addressing for 2.5.
