- The code below has quite some duplicated code but this is also a prelude

- Todo: as a prelude to lua 5.3 we should use integer instead of number when
- possible. A boring job. We can use the direct variants for testing this.

- Remark: when a direct node is set, and an invalid one is passed (or nil) we
- normally get zero and that is a predefined glue, so we get a message about

- zero a dummy so that null then can be used as test.
