Comment 7 for bug 1417291

The plus sign is caused by the docs-has-sub class, which is added to the sublist by this line in docs.js:

$('ol > li:has(ul)').addClass('docs-has-sub');

I speculate that someone is trying to implement expanding/collapsing sublists, but unfortunately the Javascript line adds the class to static sublists as well. My fix is to uncomment the line. Should this cause problems for expanding/collapsing sublists, they have to be implemented differently.
