Yes, but it works only for HTTP->HTTP proxying.  The connection to
the server, which doesn't use HTTP at all and is usually made to port 5555,
doesn't use the $http_proxy at all.

Yes, documentation to explain this fact.  I didn't anticipate it when I
added $http_proxy support, but last week I saw a different program that
uses $http_proxy in just this way.

Yes, if the proxy supports the Freeciv protocol.  (It must be a
Freeciv->Freeciv passthrough proxy, not involving HTTP in any way.
These products usually aren't called proxies, but port forwarders
or firewalls or something like that.  They can make the Freeciv server
appear on a port of the proxy system, so you can specify that port
in the Freeciv client.  E.g. the Unix SSH server, sshd, supports this.

I don't know whether your proxy software supports this.
