Look good, @vikpe .

But it will still contain those ???? packet separation characters, right? Do we want to remove them?

Those are coming - I think - from SV_FlushRedirect() in sv_send.c: `void SV_FlushRedirect (void) { char send1[OUTPUTBUF_SIZE + 6];

if (sv_redirected == RD_PACKET)
{
    send1[0] = 0xff;
    send1[1] = 0xff;
    send1[2] = 0xff;
    send1[3] = 0xff;
    send1[4] = A2C_PRINT;
    memcpy (send1 + 5, outputbuf, strlen(outputbuf) + 1);

`

Those 0xff characters, exactly 4, should be those ???? things.

Now, as we don't know who or what uses them, maybe add an exception in SV_FlushRedirect() that if this is a 'laststats' call, we don't add those into the beginning of the packet. What do you think?

All connectionless packet commands use them, lets keep it that way.
