[wp-hackers] Hierarchical Taxonomies permalinks

[Ken Newman]

Working with a custom Hierarchical Taxonomy, I've noticed that the 
permastructure does not append the parent term to the permalink.

example.com/taxonomy/parent/
example.com/taxonomy/child/

In a default post category permalink, the parent is appended.

example.com/category/parent/
example.com/category/parent/child/

Anyone have a way to make custom taxonomies behave more like categories?
