MatchPageNames() already knows how to deal with arrays and multiple
patterns, so let it do the loop instead of you doing it.  Better:

  $CommentNameFmt = array(
      '{$Group}.*',          // all pages in current group    
      '*.{$Name}-Comment',   // pages with -Comment prefix in any group
      '{$FullName}-Talk',    // page with -Talk prefix in current group
      '{$FullName}-Discuss', // page with -Discuss prefix in current group 
      'Comments.{$Group}-{$Name}', //pages in Comments with name 'Group-Name'
      '-$SiteGroup.*'        // no pages in SiteGroup
  );

  $CommentPermission = 
    (boolean)MatchPageNames($targetname,
                            FmtPageName(implode(' ', CommentNameFmt),
                                        $pagename));
