Oh dear. Am I to blame for this?

When I reported the newline issue, somewhere in the back of my mind I
knew it probably would have some ugly consequences. Now I see them. 

An evaluated code block seems inelegant/confusing if one intends to
export that code as part of the document. A data reference seems OK, but
I take it you can't have references within it?

Unfortunately, I see no easy solution...
