[PATCH/RFC v2 2/2] use the new git_default_config()

[Tanay Abhra <tanayabh@gmail.com>]

If we change the signature to void git_default_config(void),
we would have to use a patch like this to change the call sites
of the function. This patch is just for illustrative purpose,
I couldn't finalize if this was unnecessary code cruft or
a valid approach.
