Paragraphs – should they contain line breaks?

Reviewing the documentation from Stoical[1], it occurs to me that fixed line length text is archaic. I'm new to the Linux/C/Git world of things, so I don't want to be rash. (and it seems like a great question for a Friday afternoon)

Is it reasonable to get rid of all the extra line breaks and make something that flows better on all screen sizes?
