Double include of getopt.h in env.c and groups.c (coreutils-6.12)

[Jerry Snitselaar]

Is there a reason that getopt.h gets included twice?

src/env.c:

#include <getopt.h>
#include <sys/types.h>
#include <getopt.h>

src/groups.c:

#include <getopt.h>
#include <sys/types.h>
#include <pwd.h>
#include <grp.h>
#include <getopt.h>
