    [2150] Allow RBTree::find() to start at a lower level
    
    Note that if a previous find() results in a PARTIALMATCH, the next
    find() (when passed a populated node chain and a non-absolute label
    sequence) starts at the down-node of the partial match's top of chain
    (deepest matched node). The caller must pass the correctly formed
    non-absolute label sequence for that sub-tree-of-tree.
