Add a 'display-occur-buffer-action' variable and use it as ACTION
argument in that call.  Something that IMHO should have been used
wherever we currently bind 'display-buffer-overriding-action'.

Any such let-binding would affect nested 'display-buffer' calls that are
completely unrelated to the action you want to fix.
