In zed's _finish_daemonize(), /dev/null is open()d onto a temporary file descriptor which is then dup()d onto stdin, stdout, and stderr. But if file descriptors 0, 1, or 2 are not already open at the start of this function, then the temporary file descriptor will fall within this range and be inadvertently closed when the function cleans up. This commit adds a check to prevent inadvertently closing this (presumably temporary) file descriptor when it shouldn't.
