commit 2d8fefc484274b740933541778ae7ce1ae1045e7
Author: Fabian Keil <fk at fabiankeil.de>
AuthorDate: Sat Mar 6 11:52:10 2021 +0100

    serve(): Close the client socket as well
    
    ... if the server socket for an inspected connection has been closed.
    
    Privoxy currently can't establish a new server connection
    when the client socket is reused and would drop the connection
    in continue_https_chat() anyway.
