Re: toggle-viper-mode strangeness

[Richard M. Stallman]

Here's what that code does:

              (if (eq viper-mode t)
                  ;; Turn the mode off.
                  (viper-go-away)
                ;; Turn the mode on.
                (setq viper-mode nil)
                (viper-mode)))

It looks correct to me, except perhaps for the eq call,
which treats non-nil non-t values as "off" rather than "on".
That is peculiar, but I don't know whether it is wrong.
