Hmm. Rather than revert it outright, it might be better to make it use the 
nicer parsing functions and "struct tree_desc".

It shouldn't look _that_ different from the "struct tree" version: instead 
of doing

	item = item->next;

it would do

	update_tree_entry(tree);

instead.

Give me a minute, I'll send you patches.
