[wp-hackers] patch for list_cats

[Adi Jörg Sieker]

Hi,

after reading this question 
http://wordpress.org/support/topic.php?id=21226 and playing around
with wp_list_cats. I found that this isn't 100% possible because when
you call wp_list_cats("children=0&child_of=3"); I would have expected 
the children of cat 3 to appear but not the children of the children. In 
the current implementation of list_cats nothing gets displayed. The 
attached patch allows list_cats to only display the direct decentants of 
the parent cat.

Regards
    Adi
