Hmm... so now we need to figure out whyh my code works differently
from your.  Maybe it's just a silly bug in my code, but maybe there's
something deeper.

I believe you.

I'm talking here about fixing display-buffer not just
display-buffer-other-frame.

Maybe, maybe not: maybe the raise is the part that makes it work.
That's what I'm trying to figure out.
