When using ebuffers with the default settings, going up and down on
differences by pressing n and p switches focus to the buffers that are
being compared. As an example, run the following commands in terminal:

ping -c 10 example.com > ~/fileA
ping -c 10 example.com > ~/fileB
emacs -Q --eval '(ebuffers (find-file "~/fileA") (find-file "~/fileB"))'

and then press n and p to navigate through the differences. You will notice
that focus switches to the buffers. It doesn't happen always.
