Pygit2 cannot parse URLs with OAuth tokens.

I'm trying to use pygit2 to clone a GitHub repo using OAuth tokens.
This actually works well from the command line, as explained on GitHub's blog here.

So, I do:

from pygit2 import clone_repository

oauth_token = 'somesuperlongtokengivenbygithub'
repo = clone_repository(
                'https://'+oauth_token+'@github.com/openwrt/luci', 
                '/tmp/repos', 
                bare=True
)

and I get back:

_pygit2.GitError: Unsupported URL protocol

pygit2/init.py に示されている clone_repository 呼び出しから始め、URL が errors.py のエラーチェックにどのように到達するかを調べます。OAuth トークン URL のケースを再現し、issue に記載されているコマンドラインの動作と比較して、既存の URL 処理または認証処理のどれが適用されるかを判断します。完了条件は、clone_repository がドキュメントに記載された GitHub トークン URL を Unsupported URL protocol を発生させずに受け入れることです。
