Bug#68923: Getopt long options example needs rewriting

["H. Nanosecond" <aldomel@ix.netcom.com>]

Package: glibc-doc
Version: 2.1.3-10
Severity: wishlist

The example givin in the '(libc)Getopt Long Options' node is messed up,
as it looks unlike any GNU program I have seen.

It should use NULL instead of 0 as a pointer and should use the 
constants no_argument, required_argument and optional_argument instead
of 0 and 1 in the second element in these lists below.
And the fourth place is typically the short option.

It says now
           static struct option long_options[] =
             {
               /* These options set a flag. */
               {"verbose", 0, &verbose_flag, 1},
               {"brief", 0, &verbose_flag, 0},
               /* These options don't set a flag.
                  We distinguish them by their indices. */
               {"add", 1, 0, 0},
               {"append", 0, 0, 0},
               {"delete", 1, 0, 0},
               {"create", 0, 0, 0},
               {"file", 1, 0, 0},
               {0, 0, 0, 0}

but should be like
               {"delete", required_argument, NULL, 'd'},
               {"create", no_argument, NULL, 'c'},
               {"file", required_argument, NULL, 'f'},
               {NULL, 0, NULL, 0}
