This is currently not supported.

This is the expected behaviour.

I don't understand what you're asking for here.
Can you please rephrase it?

While you can already modify the Connection header using
a client-header filter, the use of the header shouldn't
depend on whether or not Privoxy is configured to use
socks4.
