[BZ#747671] Second meld instance doesn't abort on Ctrl-C, and is not always created on the top of the windows stack

This is certainly as conventional as it can go.
I see this code, not sure why doesn't this exit:
if sys.platform != 'win32': from gi.repository import GLib GLib.unix_signal_add(GLib.PRIORITY_DEFAULT, signal.SIGINT, lambda *args: meld.meldapp.app.quit(), None)
