While this might be/sound reasonable, this is not how
svn_wc__db_scan_addition() and everything build on top works.
Added nodes are in WC-NG always added below their parent; they don't have a
URL. What is below an added tree is completely ignored for its status
Changing this, changes the entire WC-NG design in many more ways than I can
