two issues about config remote

[Aimeast]

Q1: Hereafter code produce two remote sections in the git config file.

Console.WriteLine(GlobalSettings.Version); //{0.22.0-8daef23-785d8c4 (x86 - Threads, Https)}

using (var repo = new Repository(Repository.Init(".\\test.git", true)))
{
    repo.Network.Remotes.Add("origin", @"https://github.com/libgit2/libgit2sharp.git");
}
var config = File.ReadAllText(@".\\test.git\\config");
Console.Write(config);
/*
[remote "origin"]
    url = https://github.com/libgit2/libgit2sharp.git
[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
*/

Q2: How to set a remote as mirror. I think there are no API consider about this.

[remote "origin"]
    url = https://github.com/libgit2/libgit2sharp.git
    fetch = +refs/*:refs/*
    mirror = true

Perhaps this solution?

repo.Config.Set("remote.origin.mirror", true);
