bc6bcde48f Arenainit and arenafinish no longer exist under those names, and there is no longer anything special about them, so remove design documentation.

6f196185a1 Make shield assertions robust against deep checking -- when shieldcover is called from shieldraise there is one unsynced segment that has not yet been queued. record this fact in a new queuepending flag in the shield structure. 
Remove incorrect shield assertion "shield->depth == 0 || shield->suspended" -- depth may be increased without suspending the mutator if the segment did not need protecting.
