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.
According to the link you included, the issue affects only Sphinx >= 1.4.
That explains why I've never seen these warnings (I'm using Sphinx 1.3.1).
Sounds like worth fixing, as it'll probably break Sphinx output with the newer version. Looks like this is the way to go to stay backwards-comptabile: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827622#10 I'll take a look.
Fix committed, could you two try it with 1.3 and 1.4 respectively?
Works for me.
Works for me (sphinx 1.3.1).
