Re: [PATCH] Fix display-buffer-use-some-window to honor reusable-frames

You're right. I missed the case where we first want
to reuse an existing window if the buffer is already
displayed in it. Working on a patch to add that back.

The main reason not to take that approach is that it
requires changes to display-buffer-use-some-window
like the ones I made in my first patch so that it will
honor reusable-frames (though without the incorrect
call to display-buffer-pop-up-window). It seems
like it will be easier to reason about the impact of
the changes for the patch if we only need to assess
changes to display-buffer-use-least-recent-window.
