Subject: Is "show-ref -h" a good test for an empty repository?
Message-ID: <48C1D2AE.3010001@feds.uwaterloo.ca>

Hi,

I'm trying to test to see if "git diff --cached" will fail because there 
are no existing commits.  I've come up with running "git show-ref -h -q" 
and testing its return value.  My hypothesis is: If and only if 
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.

Thanks in advance for the help!

Cheers,
