This means that you might need 4 slots in `options`, doesn't it?
Done.
This merge request was approved by Giovanni Mascellani.

This breaks building the documentation for me. Getting rid of the extra spaces/indentation before the items helps. Note that while the CI doesn't fail to build this, the resulting documentation doesn't look especially great either.

Right, I don't get a failures, but a million warnings. I'll push something to make it look better, thanks.
