Sorry, I didn't notice that you've pushed that already.  So

+To change which window is used, set `display-buffer-base-action'
+to a list containing one of these \"action\" functions:

is another wrong interpretation - a user should not set (or at least not
start with setting) `display-buffer-base-action'.  The user's domain is
`display-buffer-alist' the application's domain is the ACTION argument.
Please try to stick to these two, maybe not even mentioning the rest at
all.
