It is a check if dst_cp_relpath is the root node or any of its descendants.
The root of a move can never be shadowed (as the maximum op_depth of a node
is its own op depth... which is the move)
A string comparision is quite heavy if we really only need this check. (The
db query already assures that there will only be nodes at or below
dst_relpath)
