If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

I agree that the newline should be removed. The comma is fine, or fine to remove; I would probably write it, but I also know I tend towards using more commas than most people, and it reads fine either way.

[GuillaumeGomez]

It's just details, but in this case, I think that the comma is slowing down my reading needlessly.

[dns2utf8]

Hm, I like the commas, the seperate the sentences so well.

[dns2utf8]

Oh, I noticed I use a lot of them myself 😄 Removed them.
