Checked that in also (as discussed with Jonathan on lwip-devel).

BTW: is there any need for pcb->mss to be set in tcp_connect() also (when it is already set in tcp_alloc() and never changed until receiving an MSS option)?

As discussed on lwip-devel, pcb->mss should be set to pcb->mss (or TCP_MSS if that's smaller, to save memory) until an MSS option is received from the remote host.
