Wishlist item.

Hi,

I tacked setting window/iconified window titles into term/xterm.el, but
found a quirk I suspect is related to Bug#18137 (which refers to
42fe2e88d and Bug#15025).  Because clients don't always have focus,
opening a new client won't trigger hooks that I would think trigger,
perhaps even after-make-frame-functions or window-size-change-functions.
