title: Plural definition is ignored for zero quantity
body: <p>I use <a href="http://developer.android.com/guide/topics/resources/string-resource.html#Plurals" rel="noreferrer">plurals</a> to compile a quantity string for an Android application. I follow exactly what one can find in the tutorials:</p>
  
  <pre class="lang-java prettyprint-override"><code>res.getQuantityString(
      R.plurals.number_of_comments, commentsCount, commentsCount);
  </code></pre>
  
  <p>Here is the definition of the plurals:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
      &lt;plurals name="number_of_comments"&gt;
          &lt;item quantity="zero"&gt;No comments&lt;/item&gt;
          &lt;item quantity="one"&gt;One comment&lt;/item&gt;
          &lt;item quantity="other"&gt;%d comments&lt;/item&gt;
      &lt;/plurals&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>Interesting enough, the output string is odd to what I definied:</p>
  
  <pre class="lang-ruby prettyprint-override"><code>commentsCount = 0 =&gt; "0 comments"  
  commentsCount = 1 =&gt; "One comment"  
  commentsCount = 2 =&gt; "2 comments"
  </code></pre>
  
  <p>I guess this is because the docs state <code>When the language requires special treatment of the number 0 (as in Arabic).</code> for <code>zero</code> quantity. Is there any way to force my definition?</p>
