Simply paste the following code on your function.php file:
function canonical_for_comments() {
global $cpage, $post;
if ( $cpage > 1 ) :
echo "\n";
echo "<link rel='canonical' href='";
echo get_permalink( $post->ID );
echo "' />\n";
endif;
}
add_action( 'wp_head', 'canonical_for_comments' );
Thanks to I like WordPress for the useful tip!
