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.

Thanks. This needs a NEWS entry, and I think there should be a
defcustom to turn this off, for those who'd like the default title
provided by xterm.

Maybe one of the hooks provided by server.el would fit the bill?

Nope, none of those appear relevant, and hooking into them does nothing
apparent. Even doing the following, I get the title as the selected
buffer in the previously selected frame.
Messaging (frame-list) in xterm-test shows that the car of the list is
always the new frame, but still the frame title is incorrect--a new
frame created by emacsclient -t ends up on the scratch buffer. I say
"ends up" because sometimes I see another buffer flash before I see the
scratch buffer. This all seems a little buggy to me, but I know
Bug#18137 and its ancestors were tough.

What about window-configuration-change-hook, does that help? You
could set some flag in after-make-frame-functions, and then test and
reset that flag in window-configuration-change-hook, when you see that
a buffer is switched in the frame. Would that work?

This appears to work, thank you. Please see attached.

Thanks, this LGTM. It needs a NEWS entry about the new defcustom, and
then it can go in.
