Modify confusing words and add explanation to git diff with Head

[erinmgraham]

Closes #607

Slight adjustment to the explanation of using git diff with HEAD and previous commits. The original text was great, and I've just rephrased it for clarity and consistency. The new text emphasizes that omitting HEAD doesn't change the command's output and highlights the power of comparing with previous commits using ~1.
