Thanks for working on that. Nits in env.c:

  +  if (opt_nul_terminate_output && program_specified)
       {
  +      error (0, errno, _("cannot specify --null (-0) with command"));
  +      usage (EXIT_CANCELED);
  +    }
  +
  +  if (newdir && ! program_specified)
  +    {
  +      error (0, errno, _("must specify command with --chdir (-C)"));
  +      usage (EXIT_CANCELED);
  +    }

Each of those uses of "errno" should be "0".
