Bug(s) in parse_args and/or elsewhere

[John Darrington]

in poke.c(parse_args) there is the code:

 case 's':
        case SCRIPT_ARG:
          {
            int ret = pk_cmd_exec_script (optarg);
            if (!ret)
              goto exit_failure;
            poke_interactive_p = 0;
            break;
          }

However pk_cmd_exec_script is written such that it returns zero on success.
Hence poke exits with failure when it succeeds and exists with success when it 
fails.

It seems there is a similar problem for the -c case.
