the problem that I got  cases  like  *-Issue-3-Comment-2. PmWikis 
basename function  removes alle patterns. So I changed
the code above to:

$FmtPV['$IssueBaseName'] = "StripBaseName(\$pagename,'-Issue-')";
$FmtPV['$CommentBaseName'] = "StripBaseName(\$pagename,'-Comment-')";

function StripBaseName($pagename, $pattern) {
    $basename = explode($pattern,$pagename);
    $basename = $basename[0];
  return $basename;
}


this works for :
    {$IssueBaseName{$:Title}}

but not this:
    {$IssueBaseName{$Title}}

is it possible to get the $Title value for a page in a pagelist in a way?
