the 1.3.11 version of the professional theme has the following for /links/linkdetails.thtml:
Text Formatted Code
<li>
<strong><a href="{link_url}" title="{link_actual_url}">{link_name}</a></strong> ({link_hits}) {link_edit}<br>
{link_description}
</li>
notice the title attribute in the anchor tag... that will give you the actual url when your mouse hovers over the link (like an alt attribute for an image). It does not change the link to potal.php however, because, as Dirk has said, this is necessary for hit counting..
