Ugh. Why the crazy update_jump_label script stuff? I'd go "Eww" at
that too, it looks crazy. The assembler already knows to make short
2-byte "jmp" instructions for near jumps, and you can just look at the
opcode itself to determine size, why is all that other stuff required?

IOW, 5/7 looks sane, but 4/7 makes me go "there's something wrong with
that series".
