note 46147 deleted from function.mysql-insert-id by betz

Note Submitter: ben at blarg dot net ---- minor correction to note created by crusaderky-at-libero-dot-it. I was confused by crusaderky's comment. When mysql_db_query() runs an insert command, the return value is always a boolean, and never any kind of mysql resource. Because mysql_insert_id() is only useful after running an insert command, passing it the return value of mysql_db_query() will never yield useful results. Instead, pass it the database handle returned from mysql_connect(). That handle is the "link_identifier". crusaderky makes a good case for this being a very good idea.
