title: Go - formFile for multiple files
body: <p>The formFile function works perfectly but <a href="http://golang.org/pkg/net/http/#Request.FormFile" rel="noreferrer">in the docs</a> it´s said that the "FormFile returns the first file for the provided form key". Is there a way of obtaining the several files that an html form with an input like:</p>
  
  <pre><code>&lt;input type="file" name="myfiles" multiple="multiple"&gt;
  </code></pre>
  
  <p>might return?</p>
