Are you sure you cloned it using the ssh url?
The url for origin says url = https://[email protected]/Nicolas_Raoul/therepo.git
so if it is using https it will ask for password irrespective of your ssh keys.
So what you want to do is the following:
open your config file in your current repo ..
vim .git/config
and change the line with the url from
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = https://[email protected]/Nicolas_Raoul/therepo.git
to
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:Nicolas_Raoul/therepo.git
