It's not just test cases. Some GNU programs set optind=0 and expect thisto cause getopt_long to rescan. The Coreutils programs env, nice, andstty all do this. This suggests that getopt_long should keep thisbehavior and its documentation, and that for consistency's sake getoptshould also keep doing it.
