[ESS-bugs] select-window (C-c M-j) doesn't give input focus to target (*R*) [Carbon GNU Emacs]

[David Reitter]

I understand that, in ESS-mode, C-c M-j (and friends) are supposed to  
select the *R* window and the buffer shown therein, so the input  
focus is in that window in the end.
ESS selects the appropriate frame (`select-frame') and window  
(`select-window') to do so in the function `ess-show-buffer'.

In current CVS versions of GNU Emacs (head, Carbon port) and ESS  
5.2.8, this doesn't work. The *R* window is selected by `ess-show- 
buffer' (as I have verified, both visually and by evaluating  
(selected-window)), but the input focus (cursor is solid block, not  
frame) remains on the original window. As soon as keyboard input is  
made, the source window gets selected again (visibly).

To reproduce:
Arrange two frames: one showing just a buffer in R-mode, the other  
one showing the *R* process buffer. Enter some R code into the first  
buffer. Try to evaluate a line from within the first buffer by typing  
C-c M-j. This reliably produces the bug.

Additional info:
There has been a change to the behavior of display-buffer (doesn't  
select target frame any more) a few weeks ago, which should have  
brought the display-buffer in line with its documentation.

I'm not sure if this is a problem with ESS or with (Carbon) Emacs -  
please excuse the cross-posting.
