Right. These tests were originally written as a one-page humanistic test:


It was suggested that the tests were converted to reftest format. I

And, as you have noticed, some of the tests are not very meaningful
when converte to reftests. I don't know of a way to render the text
without using columns in a way that guarantees exactly the same line
