view-exit-action is a variable defined in ‘view.el’.
Its value is nil
Automatically becomes buffer-local when set.
Documentation:
If non-nil, a function with one argument (a buffer) called when finished viewing.
Better add an example of how to set "a function with one argument". Thanks.

I don't see why we should add an example of how to use setq or customize
in an otherwise unrelated docstring. Or did you mean an example of how
to write a function with one argument? I'd say that belongs in the
elisp manual.

I finally found an example:
(setq view-exit-action
(lambda (buffer)
(or (window-minibuffer-p (selected-window))
(when (eq (window-buffer) (get-buffer "*Help*"))
(if (one-window-p t)
(delete-frame)
(delete-window))))))
So I think view-exit-action's docstring should have and example of what
they are expecting.

To me this example is confusing since the BUFFER argument is nowhere
used within the lambda.

That's what I'm saying: without a proper example users will only dig up
wrong examples from the net/web.

I agree, so I'm closing this bug report.
