git clean -d deletes files in junctioned directories on windows

[jdebbink]

When I create a junction to a directory within a git repository and run git clean -d, the underlying files in the directory being pointed to by the junction gets deleted.

To reproduce:

1. Using git bash, create a folder with a file that will later be a junction in a git repository.

mkdir afolder echo "some text" > afile.txt

2. Using git bash, create a repository
   git init arepo

3. Using windows command prompt, navigate to the repository and create a junction to the folder created in step 1.
   mklink /J C:\arepo\junctionfolder C:\afolder

4. Run git clean
   git clean -df

The file created in step 1 has been deleted. Should git clean -d stop when it encounters a junctioned directory and only delete the junction and not all the files in the junction?

I am afraid that support for junctions is out of the scope of any currently-active Git for Windows developer.
