AbstractRecord::delete() only returns false

[MichaelGatesDev]

In AbstractRecord.php, the delete function only ever returns false. I believe this an oversight.

    /**
     * Delete the record.
     */
    public function delete()
    {
        if ($this->_locked) {
            throw new Omeka_Record_Exception('Cannot delete a locked record!');
        }

        if (!$this->exists()) {
            return false;
        }

        $this->runCallbacks('beforeDelete');

        // Delete has an extra template method that is separate from the
        // callbacks. This is because the callbacks execute prior to actually
        // deleting anything. So the state of the record must be maintained
        // until all callbacks are done. Then _delete() template method takes
        // over and all bets are off
        $this->_delete();

        // The main delete query
        $table = $this->getTable()->getTableName();
        $this->getDb()->delete($table, 'id = '  . (int) $this->id);

        $this->runCallbacks('afterDelete');
        $this->id = null;
        // probably should return true here
    }
