Yes.  The problem is that `view-exit-action' is reset to nil after
exiting once.  This is hardly TRT when the buffer is _not_ killed.
Hence we could simplify the tail of `view-mode-exit' to

      (when exit-action
        (funcall exit-action buffer))
      (force-mode-line-update))))

Since `view-exit-action' is buffer-local I don't see any problems either
when the buffer _is_ killed.
