--- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
The bug is indeed the missing "Warning" in the *.opt files. It will also affect
other things like --help=warnings.

I think sending a patch that fixes all cases at once should be ok. If you have
time, I would appreciate if you could do that. Unfortunately, my free time is
very limited these days.
