CVS still makes use of it bacause we can parse a line like:

   cvs -fq -d /cvsroot checkout -P -d newname module

and getopt with a "+" as the first character of the option string kindly
stops when it reaches the CVS command "checkout".  We can then dump
everything up to optind:

    argc -= optind;
    argv += optind;
    if (argc < 1)
        usage (usg);

and reuse getopt, with a new option string, to parse the arguments to
checkout.  I don't think users would appreciate having to preceded all
CVS commands with a "--" argument.

   cvs -fq -d /cvsroot -- checkout -P -d newname module
   cvs -fq -d /cvsroot -- update

It's a bit redundant.
