It is wanted this way for all the utilities of src/bin. See
handle_help_version_opts() in src/bin/scripts/common.c for your case.

Why? We could change handle_help_version_opts() to track the instances
of --help/-? or --version/-V in the whole set of argc but:
1) This would change a behavior that has been like that for a long time
2) To which one should we give priority if both are specified
3) I am expecting someone else to show up and say that this is spec-compliant
Still arguably that's a feature, not a bug.
