I agree.

Thanks for pointing this out.

So it turns out that arguments are tested via `ange-ftp-switches-ok'.
So the easiest fix would probably be to extend this function to do a
better job of checking.  Unfortunately, I don't know if one can easily
predict which ls commands will be understood and which not?  E.g. does
ftp ls depend on the host systems version of ls?

Thanks,
Rasmus
