These comments are somewhat easier to read when there are line-breaks, why do we need to make them a single line (same for the other changes)? (I personally write mine with <=80 char width but we don't enforce it, sub-80 is most prominent in the project though.)

I admit that I changed the line length as I stick to <=120 or <=160 chars (widescreen). I believe that times with <=80 chars are already gone :)

As we fixed the bug with<br>, I guess that we can bring the original multi-line comment back.

😅. For me it's not about the space, I just find long lines harder to read because my eye needs to travel more sideways.

I also admit I like it when comments align closely to the thing they describe 😆 (like this):

In theory, we could involve one more formatter,golines, to enforce a specific line length limit, but maybe let's leave it aside from this PR.
