Do not set the gitconfig option globally
Do not set the gitconfig option globally

When we are in the git-init binary we are launching the `git config` commands
with the option `--global`.

When someone run our tests with the newly added tests for git-init it would
modify the developer .gitconfig which can be pretty bad. (i.e: it would add
http.sslverify=False to the developer gitconfig)

We do not need to modify the gitconfig globally, we can use the .git/config from
the repository.

Let's remove this switch then.
