I cannot follow your description and explanation.

What is the problem you encountered? What did you expect? What did you 
observe? Which lines of code are involved? What git command is called?

Why do you expect a certain behaviour?

I would bet that you misunderstand git and git is not broken; so, convince 
us on the mailing list that I lose this bet.

You can do better explaining, then we might help you.
