fossil --httptrace sends its cards uncompressed under this type, and the server refused it with a bare 415 on the premise that the reference client never sends it. The exchange now tells handleXfer whether the body is a zlib container or plain cards; the reply is framed as before, and fossil reads the reply's framing off the reply's own content type. x-fossil-uncompressed stays reply-only. check-in: cc96464a51 user: dmestas tags: trunk
