Would you edit your scripts to check for both nil and false (i.e.,
"not status")? My intention, which is not reflected in the NSEDoc, was
that the first result could be anything that evaluates to false in a
condition. It's sort of like the difference between
        if (cond)
and
        if (cond == 1)
in C; usually you prefer the former because 1 isn't the only "true"
value. We could just standardize on false always, but I like nil because
it's closer to what the standard Lua functions do.

I'll update the NSEDoc.
