I think this is called `save-window-excursion`.

FWIW, I think `save-window-excursion` is never the right solution
because it doesn't take into account the case where `pop-to-buffer`
uses another frame.

I can never remember which is the function to "undo" a `display-buffer`,
but I believe it's something like `quit-window` or `bury-buffer`.
We should add a reference to these in the docstring of `display-buffer`
and `pop-to-buffer`.

I wasn't sure whether that macro would survive the call to
recursive-edit, but I guess it would.

So would a quit-buffer before killing the buffer have fixed the problem
here?

It does the same as your code, yes.

I'm not sure, to be honest.
I'd use a `save-current-buffer` to be on the safe side.

Well, quit-buffer doesn't exist, but bury-buffer did (and didn't help
much here).  Both it and quit-window has the problem that the buffer in
question may be killed at this point, and the user has just exited the
recursive-edit by other means, so using either entails some checking,
and doesn't really...  help that much?

So I just changed it to a save-window-excursion.
