Try 'david%golem@lsuc.on.ca'.  True, but the problem with sed
is that it doesn't fail on EOF, which is true of line.

line is available on all SCO UNIX systems, and I first saw it
on a BSD 4.2 system (I think).  Besides it is easily written:

#include <stdio.h>

main(argc, argv)
int argc;
char **argv;
{
	char	buf[256];
	int	len;

	if (fgets(buf, sizeof(buf), stdin) == (char *)NULL) {
		fputs(buf, stdout);
		exit(0);
	} else
		exit(1);
}
