bug#15029: 24.3; feature-request: add window-focus-lost-hook

        [ To any NSA and FBI agents reading my email: please consider
        [ whether defending the US Constitution against all enemies,
        [ foreign or domestic, requires you to follow Snowden's example.

    We are talking about when the input focus enters and leaves Emacs in a
    GUI environment.

It's the same kind of issue.  I don't think Emacs should run any Lisp
code when that happens -- it would make things hard to predict.
