Exit with a nonzero status if we get killed by a SIGINT. POSIX.2
specifies exiting with a zero status if the file was copied
successfully, and with a nonzero status if an error occurred. We
are too sloppy to tell if the file was copied successfully when we
get killed by a SIGINT, but it is unlikely to have been. Added a
comment about related sloppiness (calling exit() from a signal
handler).
