Discussion:
In paragraph 9 of section 26 [algorithms], it is written:
In the description of the algorithms operators + and - are used for some of the iterator categories for which they do not have to be defined. In these cases the semantics of [...] a-b is the same as of
return distance(a, b);
Proposed resolution:
On the last line of paragraph 9 of section 26 [algorithms] change "a-b" to "b-a".
Rationale:
There are two ways to fix the defect; change the description to b-a or change the return to distance(b,a). The LWG preferred the former for consistency.
