bug#58440: 27.2; Exit Code on SIGINT is Zero, But shouldn't Be

It's by design, more or less: see handle_interrupt_signal in keyboard.c. 
Whether that design is desired or not is a different matter.

(C-g should probably not generate a signal in the first place; it creates more 
problems than it solves.)
