title: Why the highlight.js ignores the language classes?
body: <p>I'm using the <a href="http://softwaremaniacs.org/soft/highlight/" rel="nofollow">Highlight.js</a> library for syntax highlighting of code in Blogger and it refuses to highlight Lisp code properly.</p>
  
  <p>In the article on Blogger:</p>
  
  <pre><code>&lt;pre&gt;&lt;code class="lisp"&gt;
    (coerce (average 1 2 3 4) 'float)
    &gt; 2.5
  &lt;/code&gt;&lt;/pre&gt;
  </code></pre>
  
  <p>In the design template before the closing <code>&lt;/head&gt;</code>:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;script src='http://yandex.st/highlightjs/7.0/lisp.min.js' &gt;&lt;/script&gt;
  &lt;script src='http://yandex.st/highlightjs/7.0/highlight.min.js' &gt;&lt;/script&gt;
  &lt;link href='http://yandex.st/highlightjs/7.0/styles/github.min.css' rel='stylesheet' /&gt;
  &lt;script type='text/javascript'&gt;
    hljs.initHighlightingOnLoad();
  &lt;/script&gt;
  </code></pre>
  
  <p>Upon opening the article the highlighting is broken, Firebug shows this in the HTML panel:</p>
  
  <pre><code>&lt;pre&gt;
    &lt;code class="lisp ruby"&gt; // WTF
    ... stylized RUBY tokens here ...
    &lt;/code&gt;
  &lt;/pre&gt;
  </code></pre>
  
  <p>On some code snippets highlighter puts <code>&lt;code class="lisp undefined"&gt;</code> and refuses to highlight at all. As I'm on a Blogger, I really don't want to download anything to anywhere, especially when there is already published language packs. What magic should I do for Lisp to become recognizable?</p>
