I agree with both points. I have made the changes and also renamed x,y to b,c in 12.12.3.

As for 10.6.4 "Extended interval comparisons", discussed by Vincent & Oliver, I personally prefer "equals" on the ground that it is then (I think) a unique name not used elsewhere in the text. It is a small difference that humans might not notice, but a compiler certainly will notice.

I still need to think about Vincent's "comments on the comments" of 10th Feb.
