bug#4702: 23.1.50; named frame switching in terminal + emacsclient

From: Jose Antonio Ortega Ruiz
Subject: bug#4702: 23.1.50; named frame switching in terminal + emacsclient

There seem to be several situations where, if one has more than one
frame in a terminal-based emacs session and opens another one in a
different terminal, the frame selected in the first terminal changes as
a consequence. 

You can reproce the effect in a simple way:

 (0) emacs -nw -Q -daemon
 (1) open a new terminal and execute `emacsclient -t' (you're in frame F2)
 (2) eval (make-frame '((name . "test"))) (you're still in frame F2)
 (3) open a *second* xterm and `emacsclient -t' in it
 (4) the frame focused in the first terminal (opened at (1)) is now in
     frame "test", instead of F2

The frame jump does *not* happen if the frame you create in step (2) has
no name parameter (i.e. Fn is assigned by `make-frame'
internally). These frame jumps happen in other situations, but they're
difficult to reproduce; they always involve some activity by a second
emacsclient, and always have an explicitly name frame as
destination. Also, sometimes they're provoked also by calls of the form
`emacsclient -e <exp>', instead of -t as in (3), but not in this simple
