title: AngularJS: consider string with leading and trailing whitespaces
body: <p>consider the following code:</p>
  
  <pre><code>&lt;textarea class="normal_textarea" name="description" rows="4" cols="39" maxlength='79'  ng-model='newTimeline.description'&gt;
  &lt;/textarea&gt;
  "{{newTimeline.description}}"
  </code></pre>
  
  <p>the binding always trims the content in the textarea. But I need the whole content i.e.  with leading and trailing whitespaces. How can I get it?</p>
