W'de have to handle this test

  (if Info-standalone
      (save-buffers-kill-emacs)
    (quit-window)))

somehow without creating surprises for people using the standalone
version.

You might also try patching (some of) them right away so we know whether
there are any pitfalls ;-)

The problem is that the more hooks we have in one call, the more the
order in which these hooks are executed does matter.  For example, I
believe that when I run `kill-buffer', `kill-buffer-hook' is called
before `window-configuration-change-hook'.  When I run `quit-window'
with the first argument t, the order seems
`window-configuration-change-hook', `kill-buffer-hook', and possibly
another `window-configuration-change-hook' if the buffer was displayed
in a second window.  This is already very confusing for me in current
Emacs.
