Sounds fine to me.  No one has yet complained on cygwin that ls -dF turns
/ into // and // into ///, so being consistent by always appending the
slash seems reasonable for now (especially since with --color, the
appended slash is a different color than the filename).  I still have an
outstanding patch for basename/dirname treatment of //, and now that my
copyright papers are final, I should probably resubmit it for inclusion in
6.x.  That patch provides the ability to detect if // is distinct at
configure time (but in cross-compiles, must assume that // is distinct);
if anyone ever wants to avoid turning / into // we will then already have
the macro for deciding when to do the extra check.  But for now, I will
not be changing ls's behavior with / or //, even when appending the
trailing slash changes the filename printed.
