So, then to implement this in freeciv, for every unit movement into a
map
square, the server would need to check to see if a player could see that
square.  Then only if the square was visible would the unit info be sent
to the player?

I'm guessing that this could be done in server/unitfunc.c:send_unit_func
unless there is some reason that a client needs information about units
that it cannot see.
