broken large box wording change

> When you try to #force a large box or chest whose lock is already broken from a

change the wording to "lock-damaged box" and suppress
", but its lock is aleady broken" when "lock-damaged box" has
already been displayed.

(Nobody particularly likes the wording "lock-damaged box" either, but at least
it seems less misleading)
