That's strange.  So the next step is to attach a debugger to Emacs
before delivering SIGINT to it, and see why we don't exit with the
status of 1.

What I verified is that when I do

  ./src/emacs -Q -nw && echo 'OK'

and then type "kill -INT EMACS-PID" from another terminal, Emacs does
a keyboard quit (i.e. flashes the display and says "Quit" in the
echo-area), which is exactly as I expect.  So in the -nw case, the
installed SIGINT handler is called and does what is expected.
