Subject: 26.3; File opened by find-file appears in other window
Date: Wed, 13 Nov 2019 14:03:53 +0100

If find-file is used on a file that already exists in a buffer and there
is than one window then the buffer will be displayed in one of the
non-active windows. If the file does not exist in a buffer it will be
opened and displayed in the current window as expected.

The problem seems to be related to the use of pop-to-buffer-same-window
in find-file. If the definition of find-file is changed to use
switch-to-buffer (as it was in emacs25) it works as expected.

I can't reproduce that here.  Regardless of whether the file's buffer
is shown in a window or not and whether there are one or two windows,
the file's buffeer is always shown in the selected window.  Please
provide a recipe with emacs -Q.

Thanks, martin

Maybe we should look a bit deeper into this.  In the thread on
Bug#37840 we are discussing a similar issue.

It seems like we need more info here to progress.  Could you provide a
recipe to reproduce this bug starting from "emacs -Q"?
