[wp-hackers] cache_categories and category_cache

[Tara Star]

just a quickie -- I'm looking at template-functions-category.php on 
http://www.junesix.org/xref/beta/ and I see both $cache_categories and 
$category_cache used in the first two functions. Do these two cache 
variables do different things, or should they be one?

PS: looking at that to see if it's still worth trying to get 
http://climbtothestars.org/code/nested-cats.phps to work -- any input on 
that welcome, btw
