Oops. Cut-and-paste shows a bit to clearly there.

Ok, will do and send updated patch.

I was thinking specifically not providing it. This way we will find out
*really* fast if somebody adds usage of them - since the compile will
break. Then we add them once they are required.
Otherwise, we always have the risk that if it's added in a
not-often-called-place, it will take a while before anybody picks it up.
Easier to fix right away.
