snapshot: stupid debugging session
I spent a while building a little keyboard scancode printer:

  $ ./translate ex1.mu &&  qemu-system-i386 disk.img

..and wondering why up-arrow was 0x48 in hex but 724 in decimal. I ended
up paranoidly poking at a bunch of crap (though there _is_ a cool chromatography-based
debugging technique in 126write-int-decimal.subx) before I realized:

  - 724 just has one extra digit over the correct answer
  - the 0xe0 scan code is a 3-digit number in decimal -- and the final digit is '4'

There's nothing actually wrong.
