You are right, I did not test outside a git repository.
I reworked the patch and will send it after this email.

While testing my new patch it seemed to me that some of your changes in the 
patch quoted below prevent some configuration variables to be used when 
they are set in the "global" config file (~/.gitconfig). So I reverted them 
in my new patch. But thanks to your other changes, it seems to work fine 
now.

This seems to prevent using global configuration when outside a git repo.

This also.

Thanks,
Christian.
