Bold in Recent comment

Ik heb zojuist een plugin geinstalleerd die een recent comment widget laat ziet, want ik was niet tevreden met de standaard.

Echter kan ik in het script niet vinden hoe in de namen van de schrijvers dikgedrukt bold kan krijgen..

Dit is het script:

<?php
/*
Plugin Name: Recent comments widget with excerpts
Plugin URI: http://www.tacticaltechnique.com/wordpress/recent-comments-widget-with-excerpts/
Description: Duplicates the built-in recent comments widget to show excerpts instead of post titles
Author: Corey Salzano
Version: 0.111017
Author URI: http://www.tacticaltechnique.com/
*/

//	i have created two recent comments plugins. this one
//	duplicates the default widget and adds functionality
//	the other plugin replaces the default recent comments
//	widget

/**
 * Recent_Comments widget class
 *
 * @since 2.8.0
