Git clone verbose mode – show each incoming object

I accept @Lekensteyn answer.

If you want to trace git remote commands,add following environmental variables into your terminal.This helps you to peek into what is running behind the scenes of a git command.

export GIT_TRACE_PACKET=1
export GIT_TRACE=1
export GIT_CURL_VERBOSE=1
