Re: Re: Change in list-buffers behavior in 24.4

that file buffer the buffer list window still gets opened there, replacing the buffer the

^X^B never opened the list buffer in the same window the cursor was, at the time 
the list-buffers command was executed.

Now, depending on where the buffer-list window was previously shown, it will now 
open in the same window with the cursor, and I realize belatedly, after I already 
jumped somewhere else with ^Xo.

Your explanation is correct.  The behavior is intended as a feature but
inherently breaks the behavior of `pop-to-buffer', especially when used
interactively.  I intend to fix this soonish for Emacs 25 and also post
a simple workaround you can use for Emacs 24.4.

Kindly add your observations to this thread

http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20206

so we can discuss the solution there.

And please use our conventional notation for key bindings.  That is,
write C-x C-b C-x o instead of ^X^B^Xo and RET instead of ENTER.
