make emacs switch to front unsaved buffer when quit

make emacs switch to front unsaved buffer when quit

[Xah Lee]

when quitting emacs “save-buffers-kill-terminal” 【Ctrl+x Ctrl+c】,
emacs will ask to save unsaved buffer, but doesn't switch it to front
to let you see.

Is there a hook or variable to make it so?

That runs save-buffers-kill-emacs, which runs save-some-buffers, whose
docstring says:

  You can answer `y' to save, `n' not to save, `C-r' to look at the
  buffer in question with `view-buffer' before deciding or `d' to
  view the differences using `diff-buffer-with-file'.

`C-x C-c' runs `save-buffers-kill-terminal', by default.  And that calls
`save-buffers-kill-emacs', which runs `save-some-buffers'.  It's not so obvious
which function to check for more info.

Fortunately, the prompt lists the keys you can use.  Unfortunately, it does not
point out that `C-h' will give you more help, telling you what each key does.

Also unfortunately, the doc of `save-some-buffers' (both doc string and Elisp
manual) does not say anything about hitting `C-h' and some of the the other keys
you can use.

I just filed bug #11181 for this.

i tried Ctrl+r but that doesn't work. But what i actually wanted is
for emacs to switch the buffer in question automatically.

am surprised this wasn't default, till someone asked me, and i
realized being annoyed by it too.
