Squid currently doesn't do anything with content-encoding. Nor are there
patches AFAIK to content-encode on the fly.

No. It is able to transfer-encode it as deflate/gzip though. This is
hop-by-hop compression.

The branch you need is te-modules (transfer encoding modules) the te
branch has only the code for chunked encoding.
