Comment (by asn):

 Nice!

 A few comments from a preliminary review. I would like to review it once
 again:

 - As we discussed in IRC, unit tests for the non-trivial additions would
 be great.

 - Maybe we could functionify the new duplicate code in
 `get_proxy_addrport()`. I know that Nick hates duplicate code, and I share
 his sentiments.

 - This is more of a comment to the original proposal, but isn't `PROXY
 true` a bit off in a protocol that doesn't have any other `false`/`true`
 strings? Maybe `PROXY DONE` is more appropriate? Maybe not.

 - `acked_proxy` is a bit of a deceiving name. Maybe we should change the
 variable name to imply some connection to the proxy?

 Other than that, patch looks very promising!
