Subject: Our minimum TCP MSS

Why do we advertise 512 as the default MSS if the peer has no MSS
instead of 536 ?
The code has a comment:
* Default maximum segment size for TCP.
* With an IP MSS of 576, this is 536,
* but 512 is probably more convenient.
Besides the fact that 512 is a power of 2, why do we use it?
This code seems to go back to 4.4-Lite so I'm not sure how to get the
rcs/sccs log from that.
