should still be for code too no?

[matthewlipski]

I think the only case it matters is if someone creates a block with code: true and content: "styled", which is unlikely to ever happen since code should be content: "plain". But if someone does do that, we can just parse line breaks normally. We were just checking for code before since content: "plain" didn't exist.
