No actual bug fixes here, just efficiency, consistency and

Just FYI[1] if you play with benchmarking this, backward and forward
moves have completely different efficiency patterns. Forwards lookups
the first byte in a 256-entry table and adds the result to the pointer
while backwards decrements the pointers until a byte <= 0xa0 is found.
So, well, they are hard to compare...
