Re: Incorrect advice how to restore previous window

[Richard Stallman]

The code that gives this advice handles only the simple cases.
As you have pointed out, to even try to handle the hard cases
is very hard.

We certainly don't want to do that now, and it might not be worth
doing ever.  I am concerned that the approach you have in mind,
`change-window-buffer-functions', would be the first step on a path
that adds up to lots of work.  I also see potential problems in
putting hooks on every state-changing activity in Emacs, such as
displaying a buffer in a window.
