It's pretty common for Git to send gzip'd contents, so this might
actually be necessary on day one. However, it looks like we do so by
setting the content-encoding header.

I really wonder if this topic is worth pursuing further without finding
a real-world case that actually fails with the v2.19 code. I.e., is
there actually a server that doesn't set CONTENT_LENGTH and really can't
handle read-to-eof? It's plausible to me, but it's also equally
plausible that we'd be breaking some other case.
