title: Bootstrap input-group removes padding from col-XX-X
body: <p>I'm trying to create a form that includes an input-group. I use the 'col'-classes of bootstrap to style it, but when this is combined with the 'input-group'-class, the padding of the columns are removed.</p>
  
  <p>I would like the date and name input-field to be aligned.</p>

  <pre><code>&lt;div class="form-horizontal"&gt;
      &lt;div class="form-group"&gt;
          &lt;label class="col-sm-2 col-xs-2 control-label"&gt;Date&lt;/label&gt;
          &lt;div class="col-sm-4 col-xs-4 input-group"&gt;
              &lt;input type="text" class="form-control" /&gt;
              &lt;span class="input-group-addon"&gt;
                  &lt;span class="glyphicon glyphicon-calendar"&gt;&lt;/span&gt;
              &lt;/span&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="form-group"&gt;
          &lt;label class="col-sm-2 col-xs-2 control-label"&gt;Name&lt;/label&gt;
          &lt;div class="col-sm-4 col-xs-4"&gt;
              &lt;input type="text" class="form-control" /&gt;

      &lt;div class="form-group"&gt;
          &lt;label class="col-sm-2 col-xs-2 control-label"&gt;Name&lt;/label&gt;
          &lt;div class="col-sm-4 col-xs-4"&gt;
