Not that it is important, just as a note:
I looked up today msdn while I was playing with this, they mention that
order is not guarantueed at all; FAT systems will returned file in order
they are written on disk, while on NTFS & CDFS they are usually returned
in alphabetical order. I don't know why they say "usually" :-), but they
do remark that any application should sort results if sorted order is
important.

I am not sure of use-case, but it can be a bonus to get N number of
files instead of all. If Elisp was used for scripting in some very large
filesystems maybe? I don't know.
