Re: [PATCH v2 2/4] Refactoring: connect.c: move duplicated code to get_host_and_port

> The following functions:
> 
>   git_tcp_connect_sock (IPV6 version)
>   git_tcp_connect_sock (no IPV6 version),
>   git_proxy_connect
> 
> have common block of code. Move it to a new function 'get_host_and_port'
