Cannot quit Emacs from emacs -Q if something was customized

[Drew Adams]

If, for whatever reason, something calls, say,
`customize-save-variable' on `kill-emacs-hook', the user cannot quit
Emacs at all. `customize-save-variable' calls `custom-save-all', which
calls `custom-file' to get the custom file name, and `custom-file'
raises an error for emacs -Q (as it should).

There should be some way for a user to override this and say that s?he
wants to quit Emacs anyway. Just as s?he is able to say that s?he
wants to quit Emacs even though there are unsaved modified buffers,
s?he should be able to quit in this context.

More generally, whenever any error is raised while quitting Emacs, the
error should be reported, but you should be able to choose to quit in
spite of the error, via a confirmation message. It makes no sense for
an error during quitting to prevent someone from quitting altogether.
