Sorry, I don't understand.  The requester wanted the buffer to pop up on
the right, not below.  And AFAICT the code I proposed does that.  Can
you elaborate?

What is the right way to pop to a buffer in a window to the right?  IOW,
the request was to get the effect of `C-x 3' but with the chosen buffer,
not the same buffer, in the new window on the right.
