Regarding multi line format, I think there is a strong value of being able to "scan" line after line seeing what permutations are tested. I recently fixed [JDK-8306435](https://bugs.openjdk.org/browse/JDK-8306435) --- such bugs would be much harder to make if we can easily "scan" the permutations, and was one reason why I choose to reorganise the tests.
