If we ever want to use `Optional` at all (and I would, I think it is clear
and avoids special names in many cases), we have to start somewhere (or we have
to make a massive sudden change to the Graph SPI, maybe 4.0?). I don't want to
make a fuss, I would just like to be able to gradually introduce it. Maybe not
on this PR, and maybe gradual isn't better than a big change at 4.0.

> jena-text does not respect the graph setting when using the text query cache.
> In the example attached, the dataset has two graphs; the first result is
> used for the second text query. Depending on the order, either both text
> queries are zero or both one hit when the right answer is zero, once and one,
> once.
> Note also the "graph" feature of jena-text only works with quad based
> datasets (strictly, ones that use GraphView for their graphs). General
> dataset do not. This is hidden in the pattern where there is a test triple
> pattern that the literal is actually in the graph.
