Subject: New feature : Todo edit

Now you can edit multiple message by using the mode "edit" or "e" or
"mod". Edit it with the default editor ("vim" or "$EDITOR" or
"$VISUAL").

I don't think i should put "ed" as the default editor. Because,
seriously, it's ed ... I personaly use vim so i put it instead of emacs.
