When moving a single piece of wire with xref label at the end(s), the
label elegantly follows the wire.
I wish this can be done for wires with non-xref labels attached too, but
only when both ends of the wire are included in the move. If one end is
stuck to a part or a junction, there is no need to move the label.
I realized I do a lot of these, and has to move both wire and label, or
group them before moving.
