When adding the last element to the result value of `mb_split`, the `chunk_pos` may point beyond the end of the string, in which case the unsigned `n` would underflow. Therefore, we check whether this is the case in the first place, and only calculate `n` otherwise. Since `n` is no longer used outside the block, we move its declaration inside.
