I admit to having difficulty parsing this.

Is this the reason that RFC7231 says the client should ignore
Content-Length and Transfer-Encoding?

Incidentally, sometimes you just have to fix busted peers. Today I ran
into a server that rejects TLS 1.2 when used with SHA-256, and that
rejects connections from clients offering SSLv3 and higher. That server
just needs to be fixed; there are too many clients that would have to
workaround it, and we can't be boiling the oceans to interop with every
broken peer.

I'm inclined to fix bug #39 as proposed and let you -or anyone else who
needs it- contribute any CURLOPTs for falling back to the old behavior.

This isn't useful. I'm asking for details that help me construct an
acceptable patch.

Please review the proposed patch (it's a one-liner) and the comments
about adding CURLOPTs for working around old, busted proxies.

The patch I will be sending (i.e., the patch I posted + changes to the
tests) will not have any CURLOPTs for restoring old behavior unless I'm
asked to.
