[PATCH 04/14] connect_work_tree_and_git_dir: safely create leading directories

Message-ID: <20170215003423.20245-5-sbeller@google.com>
In-Reply-To: <20170215003423.20245-1-sbeller@google.com>

In a later patch we'll use connect_work_tree_and_git_dir when the directory for the gitlink file doesn't exist yet. Safely create the directory first.
