bug#17857: 24.3; terminal issue on darwin/emacsclient

Hello,

On OSX, with emacs 24.3, the terminal management as issue with
emacsclient.

Simple case: Start emacs server, start a client, enable
xterm-mouse-mode, ctrl-z, open an other client, enable xterm-mouse-mode,
emacs will tell you that the terminal is suspended and will refuse to
enable it.

Very anoying to be able to have the mouse support only on one instance
of emacsclient.

Where it start to be a real blocking issue:

(xterm-mouse-mode t) in .emacs will fail with emacsclient, as a
workaround, I use this:
(add-hook 'after-make-frame-functions '
  (lambda (frame) (unless window-system (xterm-mouse-mode))))
which works fine.

However, due to the suspended bug, if I have one
emacsclient suspended, I any new emacsclient will crash at sartup and
mess with the terminal.

At this point, xterm-mouse-mode should work already (it's enabled globally).

If you mean `M-x xterm-mouse-mode' this should be trying to *disable*
xterm-mouse-mode.

Right, that's because it tries to disable it in all terminals.  Indeed,
we have a problem here.  The disabling (or enabling for that matter)
should not burp on suspended terminals.

Good point, we should make it work.

[ Please don't quote your lambdas.  ]

In the mean time, you can try

  (add-hook 'after-make-frame-functions
    (lambda (frame)
      (unless (or window-system xterm-mouse-mode) (xterm-mouse-mode))))

Well, it is not :) (or at least does not work), likely already considered
as suspended.

As the xterm-mouse-mode does not work, yes, I try `M-x xterm-mouse-mode',
but in does not *disable* (nor *enable*), it just say `Terminal is
currently suspended'

Thanks!, works fine (I mean, doesn't crash emacs anymore, but still no
mouse)

Version:24.5

Actually, it shouldn't (at least it doesn't with neither the emacs-24 nor
the trunk code).

I added code into trunk to ignore the suspended terminals's error.

I confirm that the trunk for 24.4 works. For the .emacs mouse mode and the
suspended emacsclient.

Just FYI, the drag fail with `Wrong type argument: symbolp,
"drag-mouse-1"', but I guess it is because of trunk. (Version emacsclient
24.4.50, revno: 117458)
