Subject: connect.c: move duplicated code to a new function 'get_host_and_port'
X-Git-Tag: v1.7.1-rc0~115^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=72a534dab016813eec71935323b197650a2c0c9d;p=git.git

connect.c: move duplicated code to a new function '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'
