[Freeciv-Dev] (PR#5465) client can see all enemy units in stacks

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

As of today the client shows stack information for all units that it
knows about, via the last PR#2053 patch (discussed on IRC but not much
on the lists).  This is an improvement on the old situation, but may not
be ideal.  The client knows about all units in the open but only about
friendly (owned) units in cities (even allied units are unknown AFAIK).

One suggestion was that transported units should be hidden from the
client.  Implementing this properly would be similar to the
pcity->client.occupied flag that the client uses (it would probably be a
punit->client.transport_used flag, or some such).  However small drawing
changes would probably also be desirable: assuming that you want to see
that the unit is occupied even if you don't know _what_ is occupying it,
the "multiple units on this tile" sprite will have to be drawn in a few
more places.

Is this a desirable feature?
