 I'm writing a plugin which will allow tag clouds which are pinned to
 particular specified categories, e.g. show me the tag cloud for all posts
 in the "documents" category. This means I need to precache additional term
 counts for these categories. Because set_object_terms doesn't pass the
 old_tt_ids I am forced to iterate all the tags in the system in case a tag
 was deleted, if the old ids were passed I'd have code execution times
 approximately ten times faster with the number of tags in my system
 (lots).

 The attached diff amends the set_object_terms action to also pass the
 old_tt_ids array.
