It will look like this instead

function wp_widget_meta($args) {
extract($args);
$options = get_option('widget_meta');
$title = empty($options['title']) ? __('Meta') : apply_filters('widget_title', $options['title']);
?>
<?php echo $before_widget; ?>
<?php echo $before_title . $title . $after_title; ?>
<ul>
<?php wp_register(); ?>
<li><?php wp_loginout(); ?></li>
<li><a href="<?php bloginfo('rss2_url'); ?>" title="<?php echo attribute_escape(__('Syndicate this site using RSS 2.0')); ?>"><?php _e('Entries <abbr title="Really Simple Syndication">RSS</abbr>'); ?></a></li>
<li><a href="<?php bloginfo('comments_rss2_url'); ?>" title="<?php echo attribute_escape(__('The latest comments to all posts in RSS')); ?>"><?php _e('Comments <abbr title="Really Simple Syndication">RSS</abbr>'); ?></a></li>
<?php wp_meta(); ?>
</ul>
<?php echo $after_widget; ?>
<?php

Then I saved the file and the offending link was gone.
