Thanks, and that's really what I consider necessary.

We agree that the change is not big or hard. It's just that
- I can't convincingly argue the change in the commit message,
- security is in the picture (and I can't argue it isn't),
- hence I *really* don't want my S-o-b on the change.

I'm not opposing the change at all, I just don't want my name on it,
because I *can't prove* that it's secure. For the restrictive prefix I
have at least public references.

Thanks,
Laszlo
