All this talk about "find -depth" reminds me:
When is USG going to straighten out <search.h> and tsearch?  The manual
(and the code) has the various search orders as
	leaf, preorder, postorder, endorder
but the real meanings of these are
	leaf, preorder, inorder, postorder
respectively.  This is an annoying nomenclature botch.
