general/g.message/main.c:

    else if (percent->answer) {
	int i, n, s;
	i = n = s = -1;
	sscanf(message->answer, "%d %d %d", &i, &n, &s);
	if (s == -1) 
	    G_fatal_error(_("Unable to parse input message"));
	G_percent(i, n, s);
	fprintf(stderr, "\n");
    }

I really don't think that fprintf() belongs there; it should just call
G_percent(), without adding any "enhancements" of its own.
