Cloned repository is dirty

首先，在 Windows 10 和 .NET Core 3.1 上使用 LibGit2Sharp 0.26.2，通过 Repository.Clone 和所示的 CloneOptions 重现报告。检查克隆结果并将其与 git status 进行比较；当新克隆没有已暂存、未暂存或未跟踪的更改时，即表示完成。

Reproduction steps

Clone remote repository to local folder

var options = new CloneOptions
  {
    CredentialsProvider = (url, user, cred) => new UsernamePasswordCredentials { Username = userName, Password = passWord }
    };
Repository.Clone(_remoteUrl, _localPath, options);

Expected behavior

git status must return nothing to commit, working tree clean

Actual behavior

git status returns
