// category-template.php
get_category_parents()
get_the_category_list()
wp_generate_tag_cloud()
start_el()

Most of these title attributes are nothing more than elaborations of the implied intent of the normal link text, e.g. "View all posts in 'category'". There are a couple of exceptions - one, in start_el(), using the category description as a title attribute, and the other in the wp_generate_tag_cloud(), which adds detail information including the number of posts in that tag to the title attribute.

While the title attribute may not be the optimal way of presenting the information, themes would be able to expose it via JS if needed, and it is adding value to the link text, so I've left them in this patch.
