Well, here's what I have so far.  The list of what's changed
is at the top of main.c.  I included everything you listed in
ldb.man for completeness.  One thing to note is that, assuming
this builds ok, if you have any games in progress, you should
wait until all your opponents have sent their messages, then
do "ldb -read" under the old ldb before switching to the
new one.  This will keep messages from being garbled until
everyone figures out what version everyone else is running.

Let me know how big the mushroom cloud is...
