commit 67613cbbd87b5b3c5b10209e6272fc8ec6405b26
Author: ache <ache@FreeBSD.org>

    a) Use strcoll() in opendir() and alphasort()
    
    as POSIX 2008 requires. It also matches now how our 'ls' works for years.
    
    b) Remove comment expressed 2 fears:
     1) One just simple describe how strcoll() works in _any_ context,
     not for directories only. Are we plan to remove strcoll() from everything
     just because it is little more complex than strcmp()? I doubt, and
     directories give nothing different here. Moreover, strcoll() used
     in 'ls' for years and nobody complaints yet.
    
     2) Plain wrong statement about undefined strcoll() behaviour. strcoll()
     always gives predictable results, falling back to strcmp() on any
     trouble, see strcoll(3).
    
    No objections from -current list discussion.
