Layouts with a single window other than "MERGED" do not work (e.g.
"LOCAL" or "MERGED+LOCAL").

This is because as the documentation of bufdo says:

    The last buffer (or where an error occurred) becomes the current
    buffer.

And we do always do bufdo the end.

Additionally, we do it only once, when it should be per tab.

There's no need to enable the diff mode differently depending on the
layout: we can enable it the same way for all cases by doing
`bufdo diffthis` before doing anything else.

If we do this on every tab, then all the windows in the tab will have
diff mbox series

Patch

diff mode enabled against all buffers, which is what we want, and in
single window tabs, the desired buffer will remain.

This way a multi-window layout like "MERGED,REMOTE" behaves the same way
as "MERGED" after closing the "REMOTE" window. A consistent behavior is
clearly what most users would want.
