Reject invalid input in int2vectorin.
Since the int2vector type is intended only for internal use, this patch doesn'tworry about prettifying the error messages, which has the fringe benefit ofavoiding creating additional translatable strings. For a type intended to beused by end-users, we would want to do better, but the approach taken hereseems like the correct trade-off for this case.Caleb Welton
