Title: Correct comment on label representation. 

* The operation being performed is negation on the *value* of the
label. The comments are talking about changing the *representation* of the
label, which could be twos complement, sign magnitude, etc.

* The comments also repeat what very clearly happens in the code:

/* Set x to its negation. */
x = ~x;

* Since `~x == ((x * -1) - 1)`, there's no need for the latter.

All in all, previous content was confusing and overly verbose.
