<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>developer.wordpress.org: Enable expand/collapse functionality for syntax-highlighted code in handbooks.
* Enqueue function-reference.js on handbook pages as well
* Wrap handbook syntax-highlighted code in similar markup the JS expects as used on coderef pages
* Modify JS to handle multiple expandable code blocks on a page
* Change styling for expand/collapse links since for handbooks only one link will be present in that section
Fixes <a href="http://meta.trac.wordpress.org/ticket/959">#959</a>.</pre>
