P0896R4 changed the term of art "sorted with respect to comparator" defined in 27.8.1 [alg.sorting.general] paragraph 5 to "sorted with respect to comparator and projection." That proposal updated the algorithm specifications consistently. However, there were uses of the old term outside of 27 [algorithms] that are now without meaning. We should bring back the term "sorted with respect to comparator" to fix that lack.

Set status to Tentatively Ready after eight votes in favour during reflector poll.
[2022-07-15; LWG telecon: move to Ready]
[2022-07-25 Approved at July 2022 virtual plenary. Status changed: Ready → WP.]
This wording is relative to N4910.
Modify 27.8.1 [alg.sorting.general] as indicated:
-5- A sequence is sorted with respect to a comp and proj for a comparator and projection comp and proj if for every iterator i pointing to the sequence and every non-negative integer n such that i + n is a valid iterator pointing to an element of the sequence,bool(invoke(comp, invoke(proj, *(i + n)), invoke(proj, *i)))
