You're not missing something -- I was missing something!  I guess it
should say `by any non-unit divisor', or clearer words to that effect.

   | Minor issue: The sentence just before the Implementation section reads:
   |
   |   Computer scientists will immediately recognize this as the interval of
   |   integers representable in two's-complement with (k - 1) bits.
   |
   | but "(k - 1) bits" should read "k bits" if I'm not mistaken.

Correct.  I mixed up the exponent of 2 in the bounds with the number
of bits in the representation.
