Perhaps the solution Sam proposed is much better then?  To read one
character at-a-time and only special-case the '\n' characters?

Maybe something like this?

	if (sflag) {
		int ch;
		time_t otval = 0;

		while ((ch = getchar()) != EOF) {
			putchar(ch);
			if (ch != '\n')
				continue;

			if (rlfag == 0 && time(&tval) == -1)
				err(1, "time");
			if (tval != otval) {
				lt = *localtime(&tval);
				badv = vary_apply(v, &lt);
				if (badv) {
					fprintf(stderr,
					    "%s: Cannot apply date adjustment\n",
					    badv->arg);
					vary_destroy(v);
					usage();
				}
				(void)strftime(buf, sizeof(buf), format, &lt);
				otval = tval;
			}
			(void)printf("%s", buf);
			if (fflush(stdout))
				err(1, "stdout");
		}
	} ...
