mdgross on "Remove "At a Glance" Theme Name"

I would like to remove the theme name from "At a Glance." The code I was using (see below) stopped working after the WordPress 3.8 update. It appears that this text is no longer filtered by ngettext.

add_filter('ngettext', 'remove_theme_from_dash');

function remove_theme_from_dash($text)
{
	if(preg_match('/Theme.*with.*widgets/', $text))
	{
		return '';
	}
	return $text;
}

I would prefer to remove the text entirely as opposed to hiding it with CSS. Thank you.
