Tłumaczenie komentarzy w przestarzałym (zdaje się) stylu

Mam nową instalację WP z dość starym jak mi się wydaje stylem prosumer 1.9. Komentarze domyślnie nie są przetłumaczone – chciałem je sobie przetłumaczyć, ale zastanawiam się, jak to robić. Plik comments.php zdaje się nie zawierać każdych słów do tłumaczenia w funkcji __() lub _e(). Powinienem, edytować właśnie ten plik?

Treść pliku comments.php:

<?php // Do not delete these lines
	if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Please do not load this page directly. Thanks!');

	if ( post_password_required() ) { ?>
		<p class="nocomments">This post is password protected. Enter the password to view comments.</p>
	<?php
		return;
}
?>
<!-- You can start editing here. -->

<?php if ( have_comments() ) : ?>
<?php if ( ! empty($comments_by_type['comment']) ) : ?>
	<h3 id="comments"><?php comments_number('No Responses', 'One Response', '% Responses' );?> to “<?php the_title(); ?>”</h3>

	<div class="navigation">
		<div class="alignleft"><?php previous_comments_link() ?></div>
		<div class="alignright"><?php next_comments_link() ?></div>
	</div>
<br class="clear" />
	<ol class="commentlist">
	<?php wp_list_comments('type=comment&callback=list_comment'); ?>
	</ol>

	<div class="navigation">
		<div class="alignleft"><?php previous_comments_link() ?></div>
		<div class="alignright"><?php next_comments_link() ?></div>
	</div>
<br class="clear" />
<?php endif; ?>

<?php if ( ! empty($comments_by_type['pings']) ) : ?>
<h3 id="pings"><?php _e('Trackbacks/Pingbacks' );?></h3>

<ol class="trackbacklist">
<?php wp_list_comments('type=pings&callback=list_pings'); ?>
</ol>
<?php endif; ?>
<br class="clear" />
 <?php else : // this is displayed if there are no comments so far ?>

	<?php if ('open' == $post->comment_status) : ?>
		<!-- If comments are open, but there are no comments. -->

	 <?php else : // comments are closed ?>
		<!-- If comments are closed. -->
		<p class="nocomments">Comments are closed.</p>

	<?php endif; ?>
<?php endif; ?>

<?php if ('open' == $post->comment_status) : ?>

<div id="respond" class="comform">
