// SIGDASH FIX: <pre><nowiki>

    }

    // The fix above doesn't work with the new fancier edit form.  Use this instead.
    // The setTimeout() trickery is needed due to issues with asynchronous script loading:
    // it seems to be the only way to ensure that the button has been created before this
    // code runs.  Otherwise this would be a two-liner. :-(
