title: Show both staged & working tree in git diff?
body: <p>If I run <code>git diff</code> I see the changes in my working tree, and if I run <code>git diff --staged</code> (alternatively <code>--cached</code>) then I see the changes that are staged (w/ <code>git add</code>) but is there a way with <code>git diff</code> to see all in one go? </p>
