Note that I referred both to scripts that are part of Git and
(actually more) to various third-party scripts I wrote externally.

Thanks!

I have actually once converted blameview to use Git locally, but in
the end never got around to submit it; I wonder if I have the source
still around somewhere. Not so important, I guess.

I don't understand. Parsing whole config happen will either happen in
git-config or in Git::Config, and the performance difference is so tiny
that it is not really worth the API complexity, I believe.

With the envisioned model, it could use $git which would be either
a reference to a Git::Standalone singleton or Git::Repo instance.
