title: git clone of git itself creates Git dir which is hardlinked to git
body: <p>The command "git clone git://git.kernel.org/pub/scm/git/git.git" clones git into a directory named git, as I expected.  I did not expect to find a directory named Git at the same level, hardlinked to git.</p>
  
  <p>Why did it do that? </p>
