title: Is there a syntax for links with no text in Markdown?
body: <p>I want to write </p>
  
  <pre><code>http://www.foo.com/ 
  </code></pre>
  
  <p>and get a link with the URL as the text (e.g., in HTML output). I do not want to write </p>
  
  <pre><code>[http://www.foo.com/](http://www.foo.com/)
  </code></pre>
  
  <p>Is it possible?</p>
