RFC 2646 describes the format for flowed text in a MIME document, i.e. it
describes a format to relaibly distinguish soft and hard line breaks that
is backwards compatible with existing MUAs.

It would be expected that the application translates between the RFC 2646
format and its own soft and hard line break convention when reading and writing
the message in a mailbox.

\n is not legal in RFC 2822 messages.  Line endings are CR-LF.  Of course
the application may its own line ending convention internally.

It would make most sense to translate from the RFC 2646 format to that used
by the GTK text widget when reading and the reverse when copying the message
back to the mailbox.  There is no need for the text widget to understand the
2646 format directly.

Hope this clarifies.
