I think it's usually important to keep the property that killing doesn't
modify the buffer's text (when used in copy-as-kill), so rather than having
before-kill-functions modify the buffer's text just before it's put in the
kill-ring, it would be more convenient to make it return the string,
i.e. use it as a replacement for buffer-substring.
