RFC 1421, Privacy Enhanced Mail (PEM)
(https://www.ietf.org/rfc/rfc1421.txt), is the controlling document.
Lines should break at 64 characters, and EOL is CRLF pairs.

 * 64-char lines is covered in section 4.3.2.4, Printable Encodings
 * CRLF is covered in section 4.3.1  Constraints

Line breaks at 64 chars is an anachronism (in my opinion), but some
software still enforces it. Some software will reject keys and
certificates if not properly broken.
