Extend field grouping class naming

Filed groups are only assigned the class "item-list":

<div class="item-list">
<h3>FIELD</h3>
<ul>...</ul>
</div>

I think it would be beneficial to add semantic classes similar to li classes:

<div class="views-group views-group-FIELD views-group-FIRST/LAST views-group-ODD/EVEN">
<h3>FIELD</h3>
<ul>...</ul>
</div>
