  POSIX does not specify anything about --help. It's a GNU extension,
like every long option.

  For true or false, POSIX does not specify any option at all:

  False is supposed to return a non-zero exit code. Nothing else is
specified. So it applies when arguments are given to false too, no
matter what those arguments are; and busybox's behaviour is non-compliant.
