git prompt: Simplify "staged" logic

Browse Source 
This had this weird "pass along the sha, then check" logic to it which
is entirely unnecessary.

This function just says when something is staged, nothing more. Why
that is you can figure out for yourself.

This makes it easier to call this function, and it no longer prints an
empty line if nothing is staged.
