[Bug] Wrong field for posts of an author

You write in single.php on line 15 (and in content.php on line 21):

<span>by <a href="<?php the_author_link(); ?>"><?php the_author(); ?></a></span> /

I would prefer following to link the author name to his/her posting archive:

<span>by <?php the_author_posts_link(); ?></span> /
