I believe that I indeed got confused. I am not very familiar with
mh-e. I use mail-mode myself. The normal mode for mail buffers in
mh-e appears to be mh-letter-mode. That one does not appear to set
buffer-offer-save, unlike mail-mode and message-mode. After my
proposed change it would, when invoked via compose-mail. I could
avoid that by checking mail-user-agent in compose-mail. But should
mail buffers not set buffer-offer-save to t, because otherwise the
user might loose work if inadvertently exiting Emacs?
`mh-compose-and-send-mail' could do it right after calling
mh-letter-mode. (I now saw that mh-e can be invoked in a way that
bypasses compose-mail).
I now believe that mh-make-folder should set buffer-offer-save to t
right after calling mh-folder-mode.
Just to be sure I'm understanding correctly, you'd like to see the
following code in mh-e.el:(mh-folder-mode), right?
(if (or mh-xemacs-flag (< emacs-major-version 22))
(setq buffer-offer-save t))
Unfortunately, to play it completely save, that might still be
necessary (even if mh-make-folder already would set buffer-offer-save
to t) because if the user switches modes in the buffer, then in prior
Emacs versions and XEmacs, the local variable buffer-offer-save will
be killed.
Also, is the setting of buffer-offer-save to nil in
mh-utils.el:(mh-find-path) still appropriate?
Yes. mh-find-path is not a major mode (or so I believe). I believe
all that one does is avoid asking the user to save a temporary buffer
(mh-temp-buffer) created by mh-find-path. Correct?
Sincerely,
Luc.
