<h3>Log Message</h3>
<pre>In `get_pages()`, `$cache` does not need to be reset to an empty array. `update_post_cache( $pages )` takes care of priming.
In `set_post_thumbnail()`, (accidental) assignment is unnecessary for `$thumbnail_html` as it is not used.
See <a href="http://core.trac.wordpress.org/ticket/27882">#27882</a>.</pre>
