After more helpful input, I’ve decided to update my original solution.

Instead of overriding four WordPress functions and adding two new ones in my functions.php file, I have slimmed it down to just one:

/**
 * If more than one page exists, return TRUE.
 */
function show_posts_nav() {
	global $wp_query;
	return ($wp_query->max_num_pages > 1) ? TRUE : FALSE;
}

This function will tell me if there is more than one page…and if there is, I will show the posts navigation (next_posts_link and previous_posts_link). I updated my WordPress (index.php, archives.php and search.php) files with:

<?php if (show_posts_nav()) : ?>
<div class='navigation'>
	<span class='older'><?php next_posts_link('&laquo; Older Entries'); ?></span>
	<span class='newer'><?php previous_posts_link('Newer Entries &raquo;'); ?></span>
</div>
<?php endif; ?>

As for the single post next/previous links, I decided to remove the check because I’ll always have more than one entry.

Much cleaner and less code
