hi Ludo, nice job!
And I tested it, it works.
But I did find some problems. Now there're three:
1. I think file-system-fold based scandir tried to traverse the whole
directories include sub-directories. It's rather slow for a deep one if I
just
    want a files list under 0 level directory tree;
2. New scandir will crash while encounters a Chinese file name. This will
be eliminated by using (setlocale LC_ALL "zh_CN.UTF-8").
    I think it's the same problem we faced in another thread. There's
something locale problem in Guile. Of course, we have a temporary solution
in recent commit;
3. It returns weird result. E.g (scandir "mmr")
==>  ("." "." "." ".." ".." ".." "aa.c" "exclude" "ml" "myecl")
There're two sub-directories, so two more dot & dot-dot added.

Anyway, I think new scandir's cool. Though it's little slow than my C wrap
version, it's more hackable.
Maybe I'll keep C wrap scandir in my project for a time. But it's
reasonable to change it to the new one in the future but depends on it's
efficiency.
