Provide a machine-processable exception which is not based on strings

When using LibGit2Sharp with a remote repository, sometimes errors occur. Those are throw as LibGit2SharpException. At this point these exceptions can only be distinguished from each other by the exception message.
Is there a way to get certain server responses like a 404 as HTTPStatusCode and not have to extract it from the message? For example, if the URL is incorrect (server exists, but path is not valid), a LibGit2SharpException is thrown which returns "invalid url, missing path" as a message. Here a HTTPStatusCode inside the Exception would be better suited to distinguish between different server responses and to react accordingly.

まず、リモートリポジトリ操作がサーバーエラーを受け取ったときに LibGit2SharpException がどのように生成されるかを追跡します。特に、issue で説明されている無効な URL の例を確認してください。メッセージに依存せずに機械処理可能な HTTP ステータスを公開する方法を判断し、404 と無効なパスのレスポンスに対するカバレッジを追加します。呼び出し側がこれらのレスポンスをプログラムから区別できれば完了です。
