I think that's a bug in `opendir'.  Here is a fragment which seems to be 
the culprit:

  dir->need_fake_dot_dotdot = 0;
  if (dir->name[1] == ':' && dir->name[2] == '/' && dir->name[3] == 0)
  {
    /* see if findfirst finds "." anyway */
    int done = findfirst(dir->name, &dir->ff, FA_ARCH|FA_RDONLY|FA_DIREC|FA_SYSTEM);
    if (done || strcmp(dir->ff.ff_name, "."))
      dir->need_fake_dot_dotdot = 2;
  }

Unless I miss something, it should have appended something to dir->name 
(like "/." or "/.." or "/*.*") before calling `findfirst', right?  I will 
submit the patches after trying this with `ls', if nobody tells me that 
I'm wrong.
