I have to agree here. Dylan, why did you want to avoid multiple
`message()`? They're not expensive afaict, so I'm not sure what the gain
would be?

I also had a try, and multiline messages only get a `Message:` prefix on
the first line, so combining them would result in unpredictable vertical
alignments. Unless there's a good reason to merge them, I'll keep them
separate.
