title: Nesting <pre> and </pre> tags
body: <p>Ok, so weird one. Is it possible to escape a <code>&lt;/pre&gt;</code> tag in a <code>&lt;pre&gt;</code> block? </p>
  
  <p>I have a project wiki in <a href="http://www.redmine.org/" rel="nofollow">Redmine</a>. It uses <a href="http://coderay.rubychan.de/" rel="nofollow">Coderay</a> for syntax highlighting, like so:</p>
  
  <pre><code>&lt;pre&gt;
  &lt;code class="JavaScript"&gt;
  
  //your JS code here
  
  &lt;/code&gt;
  &lt;/pre&gt;
  </code></pre>
  
  <p>I'm writing a wiki explaining to our users how to use Redmine. I need to document above... but this results in nested <code>&lt;pre&gt;</code> tags:</p>
  
  <pre><code>&lt;pre&gt;
  &lt;pre&gt;
  &lt;code class="JavaScript"&gt;
  
  //your JS code here
  
  &lt;/code&gt;
  &lt;/pre&gt;
  &lt;/pre&gt;
  </code></pre>
  
  <p><strong>Output:</strong></p>
  
  <pre><code>&lt;pre&gt;
  &lt;code class="[LANGUAGE NAME]"&gt;
  
  //your JS code here
  
  &lt;/code&gt;
  </code></pre>
  
  <p>The last <code>&lt;/pre&gt;</code> is missing as it closes the previous <code>&lt;pre&gt;</code> tag. Is there any way I can escape the <code>&lt;/pre&gt;</code> so that it is displayed?</p>
  
  <p><strong>Desired Ouput:</strong></p>
  
  <pre><code>&lt;pre&gt;
  &lt;code class="[LANGUAGE NAME]"&gt;
  
  //your JS code here
  
  &lt;/code&gt;
  &lt;/pre&gt;
  </code></pre>
