title: pandoc doesn't text-wrap code blocks when converting to pdf
body: <p>I'm using pandoc with xelatex engine to convert markdown to pdf. I'm running pandoc like this:</p>
  
  <pre><code>pandoc -s 'backbone-fundamentals'.md -o 'backbone-fundamentals'.pdf \
      --title-prefix 'Developing Backbone.js Applications' \
      --normalize \
      --smart \
      --toc \
      --latex-engine=`which xelatex`
  </code></pre>
  
  <p>If a code line is longer than the pdf document width it just gets cutoff. Is there anyway to have pandoc text wrap long code lines?</p>
