And, in some contexts, when forwarding e-mail it is important that we
emit exactly the line endings we received, without trying to be "helpful"
and "fix" them.  But, in the case of text content inserted into a message,
I think we should convert the system line endings into CRLF (possibly with
some way to override this - a "literal" mode).
