This is fine with me.

Well, looks like you are now suggesting that we drop the idea of having
on/off aliases, to which I disagree. How about people like me who want
this feature OFF all the time, except in rare occasions?

If you accept my view on the necessity of having on/off values instead
of just controlling this feature with a plain integer, then maybe we
have a more compelling reason?

To me, it's totally unrelated to what we are discussing. It's just
a idea that popped up during the course of this discussion. You
said that our current API for set/show commands is poorly documented.
Daniel and I offer to look into the documentation problem, and I also
suggest that this is a good time to do any cleanup if needed.
