$r['depth'] during the wp_list_comments should be $r['max_depth']

After a lengthy discussion on IRC (http://wordpress-dev.chanlogs.automattic.com/?ym=2008-10&file=wordpress-dev@2008-10-31) about the difference between depth and max_depth when it comes to the number of nested items max_depth will be better in the long run when it comes to keeping everything straight.
In customer callbacks during the wp_list_comments part, you can remove 'depth' => $argsdepth? as this patch aims to keep that away. You can always override max_depth using an argument or change the settings themselves.
