Right, the directive only displays anchors that exist earlier in the page, so 
there is an error when there is no anchor before it. We can deal with empty 
lists without issuing error messages :

  Markup('listanchor', '>[[#', '/\\(:listanchors:\\)/e', 
    '(isset($GLOBALS["SeenAnchor"])? 
      implode(" ; ", array_keys($GLOBALS["SeenAnchor"])) : "")');

The $SeenAnchor array contains all anchors that PmWiki has encountered in the 
page untill that moment when we read it in order to display the list. 
Unfortunately, I don't have an easy way to display anchors that have not yet 
been seen by PmWiki. :-)
