Cloning pathing

After cloning a path like so:

DirectoryInfo dir = new DirectoryInfo("C:/APath/SomeOtherPath/");
Repository.Clone(dir.FullName, "Some other path");

The dir.FullName returns "C:\APath\SomeOtherPath" instead of forward slashes. The clone code runs correctly, but then trying to push from the clone back to the remote repo (using Git Extensions) gives a locational error saying it cannot locate the repository.

By making the modification to
Repository.Clone(dir.FullName.Replace('','/'), "Some other path");
it was able to find the repo when pushing.

It would be a nice feature to have the slashes standardized to forward slash -INSIDE- the Clone function, or at least throw an error saying it's not going to link properly, etc.

从 issue 中描述的 Repository.Clone 入口点开始，使用 DirectoryInfo.FullName 重现 Windows 路径示例。验证克隆的 repository 是否可以用于后续 push，而无需调用方替换反斜杠；当此场景能够正常工作或产生明确的验证错误时，issue 即完成。
