help: tweak --verbose command help hint
We used to have two slightly different message which people wouldn't read...
and then complain that they couldn't find the global options or examples.
So we unify them into one message that's upfront that STUFF IS
INTENTIONALLY HIDDEN and that looks more like our normal hint style.
