[notmuch] [PATCH] To use compose-mail

Tue Mar 16 12:52:53 PDT 2010


As I wrote in the other mail, Emacs has an interface called compose-mail which uses whatever mailing mode that you’ve selected in mail-user-agent
so if you like the message mode that’s been hard-coded into notmuch.el, (setq mail-user-agent 'message-user-agent) and this will use that.

This is a simpler patch that uses as much of the output of notmuch reply as possible, at the expense of emacs more flexible hooks and citing. Both of the patches (unfortunately) still just call message-modes signature function without one of the standard hooks and wrappers, because I haven’t looked into that yet.
