I think we could design things so that existing users got git-perl on upgrades.

Right, I think were this package to exist, users would understand that
it doesn't have all of the git functionality.

Mainly, what's desired is the ability to do `git clone`, and other read-only
operations like `git checkout`, etc.

WRT Atomic, it's quite common to store Dockerfiles in git.  So here,
you want to `git clone` + `docker build -t blah .`.
