By default C-x C-q _should_ re-enter view-mode when the buffer was in
view-mode before:

     ((and (not buffer-read-only) view-read-only
           ;; If view-mode is already active, `view-mode-enter' is a nop.
           (not view-mode)
           (not (eq (get major-mode 'mode-class) 'special)))
      (view-mode-enter))

But note that Emacs 22.1 resets `view-exit-action' to nil when leaving
`view-mode' and `view-mode-enter' without argument does _not_ set it
again.
