bug#11886: 24.1; Ctrl-G in an emacs running in a terminal sends a SIGINT to the parent shell

[Vincent Lefevre <vincent@vinc17.net>]

A Ctrl-G in an Emacs 24.1 running in a terminal sends a SIGINT to
the parent shell. This can be seen with dash, mksh and posh under
Debian. For instance:

$ dash -c "/usr/local/emacs-24.1/bin/emacs -Q -nw"

$ echo $?
130

Emacs 23 didn't have such a problem.
