I think that's much what I had intended to do with not invoking binaries
at all, except that it was limited to rev-parse. I wonder if perhaps we
could do something similar if we had the `--assume-unsafe` argument you
proposed, except that we would only allow the `git` binary and always
pass that argument to it in such a case.
I don't think reading config is intrinsically unsafe; it's more of what
we do with it, which is spawning external processes, that's the problem.
I suppose an argument could be made for injecting terminal sequences or
such, though. Hooks, obviously, are definitely unsafe.
