Comment title `a` has class="active"

Issue Summary

Hello,

I am trying to customize Garland on my site and discovered the following problem.

All comments on the page are listed as "active". There is also a default CSS class property that makes them appear in a certain color, and it is also overridden by the Color module.

Isn't the "active" supposed to the used only for menu items and other lists? It doesn't make much sense to add it to the title of the comments **in the page**, since they will always be active.

Removing this class would make customizations easier.

The problem appears on Drupal.org's theme as well.
