Wow!  That command's pretty inscrutable, but I get it.

Actually, I really don't have any pressing need to do file listings of /any/
kind on Windoze, but in my book I'm discussing the use of find2perl
by Unix users to compose scripts for Jr. SAs to run on Windoze,
and I was just surprised to find that one of the most common uses
of find, "find . -ls", doesn't even run successfully on Windoze.

Don't you think it should?  If not, then maybe we need a portability
option to find2perl, to make sure it disallows the use of "-ls" with
that option, or else implements it portably.
