Our wiki is now at 1.13.1. Unfortunately, the category tree [x] feature seems
somewhat broken.

There is a category tree on the right of:
http://vim.wikia.com/wiki/Main_Page 

We see "[x] Plugin" and clicking the [x] shows "no subcategories". That's good.

However, clicking the [-] in "[-] Plugin" now shows "[+] Plugin". That's not right.

Worse is that other items like "[x] Usage" do have subcategories.

Is there any logic to how [x] behaves, or is it a bug? Or does the new system need a
few days to extract info from the database so it knows which categories have
subcategories?
