`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.
