Since we now directly expose the reverses bindings directly, we don't have to have this special-case in do_choose_window. More importantly, if the backwards binding is pressed and has the Shift key included, this will actually revert it This doesn't matter for Alt-Tab in gnome-shell, which already replaces it with a better Alt-Tab replacement, but it does matter for Alt-Esc, which switches between windows directly.
