And what's the bug?  It's quite normal for SIGQUIT to kill programs
even when SIGINT does not.  If anything, I'd say the bug here is that
SIGINT doesn't cause the listing to be aborted immediately, not that
SIGQUIT does exactly what it's supposed to do.

It's not easy.  There was an explicit prompt which you had to affirm.
