This seems fine to me. OTOH, I'm not sure the environment variable should 
be needed in the first place; I think the config stuff should look in 
git_path("config") without it, and we set the git dir to the one we're 
initializing. So I think the use of the environment variable is just an 
artifact of how the shell script did it and how I was originally calling 
the init_db stuff.

Just removing the "setenv()" line survives all of the tests for me, and I 
remember some of them failing before I'd gotten some sort of solution for 
the config stuff.

You'd think I would have noticed this, since I mainly decided to convert 
clone to C so that url.insteadOf in global config would let you do "git 
clone work:modulename", but I clearly never tested it.
