I have been watching this discussion from the sidelines, and I agree
that this direction is a big improvement.

IIRC, the "const" in git_config_get_string_const is only about avoiding
an annoying cast. The result is still allocated and needs freed. Since
you are not keeping the value after the function returns, I think you
could just use git_config_get_value().
(Grepping around, I see a few other places that seem to make the same
mistake. I think this is a confusing interface that should probably be
fixed).
