If you remove them then you get tons of warnings about variables possibly
getting clobbered. The reason is the longjmp business that's going on when
you press Control-C. (The fact that the variables would get clobbered is
not critical since they're reinitialized immediately anyway, but who am I
to argue with the compiler.)
