For the loop currently in `subr.el` I think the (cdr ptr) is OK because we use the `setcdr` to truncate the list, so that last cons (whose `cdr` may be nil) will be in the list included in the (apply ....) entry.
Indeed, now I see it, and I think (without being 100% sure) that it's OK. It's yet another obscure point of the original code, though.
