I'll get terminology wrong here, so be gentle with that (only).
cd ~/src/ ./emacs * C-x 2
So I've got two windows here, one above the other, and a bunch of files in my buffer list (more than 2). When I
C-x k to kill the buffer that I'm in, of course its window then shows another buffer from my open list.
From 1997 to 2014, or so, Emacs has worked hard to avoid the buffer I also have open in another pane (which is usually awesome). Recently though, when I use
C-x k Emacs just loads whatever the next-most-recently-used buffer was into the selected window .. and that's usually the buffer I already have open in the other pane. So then it looks like:
--top-bordery-border-- file #1 stuff -UUU:%--F1- [mode] --- file #1 stuff -UUU:%--F1- [mode] ---
... which can be called Silly, most times.
Has anyone who can understand my bad description, who's seen that behaviour, know how to get the older behaviour back?
