title: strange issue with embedded ruby tags
body: <p>i have started using rails 3.1.3. After running the first sample application, I saw all my ruby tags in html.erb files are strangely converted into <code> tag. 
  for e.g. </p>
  
  <pre>&lt;%= render :partial=&gt; "abc.html" %&gt; is converting to
  
  &lt;code&gt; render :partial =&gt; "abc.html" %&gt;&lt;code&gt; in html output...
  </code></pre>
  
  <p>This seems very strange to me.. Am i missing something or what?</p>
