The point isn't to introduce a link to a C manpage,
or to avoid simple english, but to avoid the wording
of "the locale-specific" collation sequence
when LC_COLLATE is in fact ignored.
I agreee that the diff is not a very good way to go about that.
But the current wording suggests that after one specifies a locale,
expr will compare strings according the that.
locale(1) describes LC_COLLATE of course,
Intended to affect collation order. It may for example
affect alphabetic sorting, regular expressions including
equivalence classes, and the strcoll(3) and strxfrm(3) functions.
so only in strcoll(3) does one eventualy read that
the locale has in fact no effect on collation.
That was the intention.
