How do you solve the problem of different argument lists in different
predicates?  And how do we allow to specify such an alternative
comparison in interactive usage?

Also, if string-collate-lessp is the only additional possibility we
can think of, why not change sort-subr to use it "when it's TRT", as
we do currently when sort-subr's PREDICATE argument is nil?  Making
sort-lines entirely open-ended like the suggestion says might be too
much.
