        [ENHANCEMENTS]
        - HTTP::Proxy::BodyFilter::save had an issue with cygwin because
          of an incorrect use of File::Spec's catdir(). This is fixed.
        - CONNECT requests are now forwarded to the upstream proxy, if there
          is one. Errors from the upstream proxy are relayed to the client.
        [TESTS]
        - t/23connect.t does not use sysread() anymore. This time the test
          should pass about everywhere.
