The top comment is the commit message so it won't be lost. I agree that
more comments are needed to describe this logic--it isn't trivial logic. I
think the discussion about what the bug is belongs in the commit message, but
what the correct logic is makes sense to be in the code. I'll add that. I think
the TDML comment should just describes what the test tests, so I /think/ that's
sufficient with good code comments.
Will modify to improve comments. No changes changes will be made.
