LGTM.

Question: Is this a fix or a breaking change? I can't arrive at a decision on that.

[jwilsson]

I wanna say it's a bug fix for a 3.0 regression, because the 2.0 behaviour was putting new lines in raws.before.

Sounds good to me. 😅 here's hoping a patch doesn't bork the world. I'll get this published later on today. Thanks for getting a fix in.
