bug#37840: Missing in the Emacs manuals:

The new option is now called 'switch-to-prev-buffer-skip' and also
accepts a function as value.  Hence Konrad can write, for example,

(defun no-occur (window buffer bury-or-kill)
  (string-equal (buffer-name buffer) "*Occur*"))

(setq switch-to-prev-buffer-skip 'no-occur)

so *Occur* will never be shown automatically, even if it is not
displayed on any frame at all.
