Should this return a hash reference? It seems like that is how we end up
using and passing it elsewhere (since we have to anyway when passing it
as a parameter).

I don't have a strong preference, and it's somewhat a matter of taste.
And maybe returning the actual hash matches the rest of the module
better. I admit I don't really use Git.pm much.
