[PATCH] test: make (kill-emacs) from emacsclient work with emacs 23.(1|2)

[Tomi Ollila]

emacsclient --eval '(kill-emacs)' makes emacs versions 23.1
and 23.2 ask user input from running emacs. Redefining
yes-or-no-p function when kill-emacs is executed for these
emacs versions in test-lib.el avoids this test problem.
---
Thanks Austin for your comments. Including 'activate' into defadvice
made it possible to use if (well, without progn...) instead of when
which makes this also marginally faster (as we're not byte-compiling
this).
