Change the loop into this:

    if (n <= marq_length) {
        printf("[%-*s]\n", marq_length, s);
    } else {
        for (i = 0; i < n + 1; i++) {
            putchar('[');
            for (j = 0; j < marq_length; j++) {
                char c = s[(i + j) % (n + 1)];
                if (!c)
                    c = ' ';
                putchar(c);
            }
            printf("]\n");
        }
    }
