Avoid memory access errors if llength() overflows llength() is currently a 'short' which can overflow and result in signed numbers if line lengths are larger than 32k. We'll fix the overflow separately, but before we do that, just use a signed int to hold the value so that we don't overrun memory allocations when we converted that negative number to a large positive unsigned integer.
