Because the syntax is "an+b" with comments on special cases of a=0, b=0 and 
negative a, but no mention of a special case of negative b. So if b was 
negative and the syntax was maintained it would be "an+-b". 

Besides the negative values of b are redundant, so I expect the exclusion of 
them to be deliberate.
