That select-window will do nothing unless BODY changes the selected
window, right?  So it isn't save-selected-window's business to do
anything about the issue at hand: it's the business of that BODY.

What is the problem with with-selected-window, exactly?

You assume the binding should be in effect while BODY runs.  But
that's not needed: you only need to do that around the call to
select-window (if at all).
