From: Jan H. Schönherr <schnhrr@xxxxxxxxxxxxxxx>
Do not wrap the second and later lines of non-rfc2047-encoded headers
substantially before the 78 character limit.
Instead of passing the remaining length of the first line as wrapping
width, use the correct maximum length and tell strbuf_add_wrapped_bytes()
how many characters of the first line are already used.
