    emacs -q
    C-x 2
    M-: (push '(:eval (if (eq (frame-selected-window)
                              (selected-window))
                          "A" "B"))
              mode-line-format) RET

Both mode-lines expose an 'A'-Marker.

In Emacs 24.3 the mode-line of the window that is not the user selected
one is marked with 'B'.

I realise this subtle change is not exactly a bug.  The old behaviour is
useful and used already, though.[1]
