Collating sequences are used inconsistently. (PR#289)

[ripley@stats.ox.ac.uk]

R 0.65.0 (and all others I have seen), Solaris 2.6.

> sort(c("a", "A", "b", "B"))
[1] "A" "a" "B" "b"
> "a" < "B"
[1] FALSE

in the en_UK locale. I don't think it is good idea that sort and <
have a different idea of ordering, so I rate this as a bug. As far as I can
see sort uses strcoll and hence the locale, and < uses ASCII.
