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).
