Fix wikibits.js script broken by last commit.  That tweaked DOM: editsections are now spans instead of divs and are inside the h# tags, so JavaScript etc. that relies on their being divs will break briefly.  However, this is the logical approach, since it will attach the editsection to the header naturally, including auto-centering etc.
