lines-changed-only should assert files-changed-only implicitly #82
Description
User intuition probably implies that the lines-changed-only option should implicitly mean files-changed-only is true, but this is not the case under the hood.
I think this is partially implemented in #81 (as part of the solution to #74), but it would be better to make the source explicitly change the value of files-changed-only if lines-changed-only is not disabled.
