Why not simply "No commits yet", saying "on the branch" is needlessy
duplicating information in the context of the status output in which
this is printed, i.e. now you have:

    $ ~/g/git/git-status
    On branch master

    No commits yet on the branch

    nothing to commit (create/copy files and use "git add" to track)

But we can just more succinctly say:

    $ ~/g/git/git-status
    On branch master

    No commits yet

    nothing to commit (create/copy files and use "git add" to track)

Since we've already pointed out that the user is on a branch.

Also, if something is worth fixing it's worth testing for, so you can
fix this test into the patch:
