Indeed, it's a problem, but crossing string boundaries makes the
behavior less deterministic.  I agree it can be useful, but I'm not
convinced it's worth the unpredictability: up-list can end up moving to
some very far away string, that's completely unrelated.  Currently noone
complains because when the cross-string jump is not useful, it's not
really worse than getting an error, but when the user intended to get
out of the current string, she'll be very disappointed.
