Ohh... What simple in DTML!

<dtml-call "REQUEST.set('rev', [])">
<dtml-in "PARENTS[:-4]" skip_unauthorized>
         <dtml-let item=sequence-item>
                 <dtml-call "rev.insert(0, item)">
         </dtml-let>
</dtml-in>
<dtml-in rev>
         <dtml-with sequence-item>
                 <a href="<dtml-var absolute_url>"><dtml-var 
title_or_id></a>
         </dtml-with>
         <dtml-unless sequence-end>&nbsp;&gt;&nbsp;
         </dtml-unless>
</dtml-in>
