I'm okay with that as an optional behavior, although I myself won't use it, as it's too dangerous.
Almost. I'd like it to be as if the user invoked 'save-buffers-kill-emacs'; that is, before killing Emacs, prompt the user about everything[1] that might be lost by killing Emacs.
This already exists as an option -- (server-stop-automatically 'delete-frame)[2], but I also find the current behavior too dangerous. My original message outlines one of the problems with the current implementation: it changes the behavior of (a) in my description above.
$ emacs -Q --daemon $ emacsclient -a "" -c foo.txt $ emacsclient -a "" -c bar.txt ;; In the first client frame: foobar ;; Insert some text C-x C-c ;; Emacs prompts "Save file /path/to/foo.txt?..." Now try the above, but call `(server-stop-automatically 'delete-frame)' first (or replace `delete-frame' with `kill-terminal'; it doesn't matter). In this case, Emacs doesn't prompt to save the file.
As mentioned earlier in this bug, I'm open to providing a patch to support options beyond the one I suggested (quoted at the beginning of this message), but I want to be sure we agree on what the options should look like so that I'm not breaking Gregory's (or anyone else's) preferred behavior here.
(Of course, all of this would remain opt-in. I don't want to change the default behavior here, since it would break years of established precedent.)
[1] Well, everything that Emacs usually asks about in a non-daemon configuration, anyway.
[2] It's not hooked up to Customize, though I don't think that would be too hard to do.
