I'm trying to test to see if "git diff --cached" will fail because there

git-show-ref succeeds then git-diff will succeed.
Are my logic and assumptions sound? I'm a bit out of my git comfort zone
here, so I'd like to get some validation from some people who know
better.
Maybe "git rev-parse --verify HEAD"?
That seems like it would work too... any reason one would be better than
the other?
