We already have an ambiguity problem. What if you want to hide when all
variables are empty, or any section is empty?

We could split this up into two separate attributes like so:

hideonvars=none
hideonvars=all
hideonvars=any

hideonsections=none
hideonsections=all
hideonsections=any


Are these attribute names ok? Anyways, this idea keeps the sytax simple
and consistant.

The default might be (the most commonly wanted behavior):

hideonvars=any
hideonsections=all
