No titles produced for Author Links despite coding for it (see fix)

I found the problem. The title attributes don't work the way you have them all throughout the module.

Wherever you have:
array('title' => t('whatever'))

You instead should have:
array('attributes' => array('title' => t('whatever')))

And since it wasn't working anyway, as a side note, if you'll just change line 291 from this:
$author_names[] = l($term->name, taxonomy_term_path($term), array('title' => t('See all stories by @author', array('@author' => $term->name))));

To this:
$author_names[] = l($term->name, taxonomy_term_path($term), array('attributes' => array('title' => $term->description)));

Then my next issue and this issue could be satisfied at the same time by allowing someone to use JQuery to do what they want the title text of each author. :-)
