I don't see how mdoc would be impacted, since that lives in the src 
repo.

As for pdf files, I couldn't tell you the last time I used the handbook 
in a pdf format, so I had to generate it by grabbing asciidoctor-pdf 
and running it on doc/documentation/content/en/books/handbook/book.adoc - 
and it produced [1].

Aside from things which I think can be addressed separately, the change 
I made in order to test the theories that pdf should work with extra 
linebreaks inserted at 72 columns, is on page 21, on the paragraph 
"The hardware requirements to install FreeBSD vary by.."

To me, this looks exactly like how I would expect it to look.
So I think we'll be fine with this change, at least for newlines as it 
relates to paragraphs.
