Come to think of it, why is that line named "index"? Conceptually, this
"diff header index" seems distinct from the "staging area index", but
calling both "index" is confusing, in my opinion.

Is there already a note about this in the docs somewhere? At the very
least, "git help diff" seems to happily use both senses of the word
without any acknowledgement that we're overloading it.
