Let me express more clear what I meant: not each command should test the flag,
but only a new function `show-buffer' used by these commands.

So for instance having

(defun foo ()
  (show-buffer new-buffer))

bound to some key (e.g. `C-c C-f').

Then after typing `C-x 4 C-c C-f', the prefix `C-x 4' will set some
special variable, and `show-buffer' called by this command will detect it
and put `this-command' to the user config alist with a flag to reuse this
user preference next time this command is called without the prefix `C-x 4'.

You have to type `C-x 4 C-x C-f' only once.  After `show-buffer' records the
fact of calling with the prefix `C-x 4' first time, it will reuse this
preference on subsequent invocations without the prefix `C-x 4'.
