title: Zend_Form::setElementDecorators $elements param doesn't make a difference
body: <p>From the docs ... </p>
  
  <blockquote>
    <p>Zend_Form setElementDecorators (
    $decorators, [ $elements = null],
    [bool $include = true])</p>
  
  <pre><code>array $decorators
  array|null $elements: Specific elements to decorate or exclude from decoration
  bool $include: Whether $elements is an inclusion or exclusion list
  </code></pre>
  </blockquote>
  
  <p>I wanted to re-use the same decorators for most of my elements ... but not the submit buttons ... I tried </p>
  
  <pre><code>...
  
  $this-&gt;addElement('submit', 'btnSubmitProject', array(
    'label' =&gt; 'Add Project',
    'ignore' =&gt; true
  ));
  
  $this-&gt;setElementDecorators(
    array(
      'ViewHelper',
      'Errors',
      'Label'
    ),
    array(
      'btnSubmitProject', 'submit' // I think I should be using the 1st (btnSubmitProject) but I have 'submit' just to be sure
    ),
    true // and false
  );
  </code></pre>
  
  <p>I tried true &amp; false for the <code>$include</code> flag. Both does not seem to make a difference. All elements are styled the same, with label</p>
