Make sure this is properly taken into account and clear. Motivated by discussions with Peter and Christoph and others. v2: - Mention that existing headings should be kept when converting existing .txt files (Mauro). - Explain that we prefer :: for quoting code, it's easier on the eyes (Mauro). - Explain that blindly converting outdated docs is harmful. Motived by comments Peter did in our discussion.
