SSH proxy speed issue

[JiapengLi]

Hi,

I use connect to proxy SSH-GIT in a socks5 tunnel, and I have the upstream data speed issue. If I disable connect and use same proxy with HTTPS-GIT, the speed is OK.

connect version: v1.105 (Mingw64) enviroment: Windows 10 / Git Bash

ProxyCommand connect -S localhost:1080 %h %p

A patch to improve upstream speed.
