(setq next-error-recenter '(4))
(occur "setq")
(next-error)

There's an error message "next-error: ‘recenter’ing a window that does not
display current-buffer."

I assume this has something to do with how occur-next-error sets things
up, or maybe there needs to be a workaround in next-error itself.
next-error-recenter works with e.g. rgrep without this error.
