1. Yes, please do make sure that `make-frame' does not change the focus. That
fix is long overdue. Thx.


2. In addition, please make `display-buffer' also DTRT in this regard.
`display-buffer' should never cause display of the buffer in another frame to
select the buffer (with its frame receiving the focus). But that is what
happens, on MS Windows for instance:

emacs -Q
(setq pop-up-frames t)
(display-buffer "*scratch*") ; with another buffer selected

The frame with *scratch* is raised and receives the focus - buffer *scratch* is
selected. This contradicts the documented behavior of `display-buffer', and it
has done so since day one AFAIK.

This is the case not only when *scratch*'s frame is created; it happens each
time `display-buffer' is called.

That is, fixing `make-frame' will not fix the problem of focus changing whenever
a buffer is displayed. There are two fixes that are needed.
