No, it does _not_ say that.  It says nothing of the kind.  It says nothing about
non-nil and non-t.  Saying nothing is not the same thing as saying you're on
your own - far from it.

There is zero reason to mention any particular non-nil value here, unless there
really is something special about the behavior of that non-nil value.  Judging
by the email replies, there is not.

There is no problem understanding what nil does.

You could have corrected this and made it crystal clear by now, by simply
changing `t' to `non-nil'.  Instead, defensive justification...
