Biblio block and Restric users to view own biblio entries

Hi
At the moment "Recent publications" block shows entries of all users even if option "Restrict users such that they can only view their own biblio entries" is on and the user has no access to them.

I suggest following changes:

function biblio_block($op = 'list', $delta = 0) {
global $user;
...
$limit = '';
if (variable_get('biblio_view_only_own', 0) ) {
   $limit .= " AND n.uid = $user->uid ";
}
$query = "SELECT n.nid, n.title
                    FROM {node} n
                    LEFT JOIN {biblio} b  on n.vid=b.vid
                    WHERE n.type = 'biblio' AND n.status=1" . $limit . "ORDER BY $block_order DESC"; 

There is probably better way of adding the $limit to $query.
There is similar problem with filter where for example author names are shown for which there will be no results.
