soft newlines not represented properly

[wberrier]

This may be a user error, but wanted to file this just in case.

I expected this mode to be able to put a space before newlines for soft lines. It almost sounded like 'use-hard-newlines should do just that.

It wasn't working for me, and I ended up doing something like the answer in:

https://emacs.stackexchange.com/questions/19296/retooling-fill-paragraph-to-append-trailing-spaces

which formatted the soft lines correctly.

So, questions:

• is messages-are-flowing intended to provide the behavior of spaces before newlines for soft newlines?
• if so, is it broken?
• if not, any interest in incorporating something like the above stackexchange answer into this mode? I think that would allow this mode to be a boxed solution for emacs and format=flowed

Spaces before soft newlines are added by the function fill-flowed-encode, in the module flow-fill.el. This is supposed to be done by message-mode before the message is sent, assuming that the variable mml-enable-flowed is true. Is that how you're using it? If not, extending messages-are-flowing to cover that use case might be a good idea.

I'm using mutt and emacs (in message mode) to compose these messages, and it appears there isn't any post-processing before sending. I guess that's the difference. Thanks for clarifying.

[legoscia]

So you're using server-mode to invoke Emacs from mutt? In that case, this might just work:

(add-hook 'server-done-hook 'fill-flowed-encode)

I guess it would make sense for messages-are-flowing to do that if it detects that the current buffer is a server buffer...

Very interesting idea, I'll play with that! Presumably the hook would need to make sure it only activates with message-mode / mail-mode or similar.

[wberrier]

Any interest in a pull request that defines another hook to add "live" line end spaces while editing in emacs?

I think it would be a great addition to this package for people who compose email in emacs and pass it unmodified to their mailer (mutt, for example).
