Bug#1029022: git should honour -c safe.directory

[Ian Jackson]

Package: git
Version: 1:2.20.1-2+deb10u6

I have a script which I use for privsep builds of Rust stuff.
Since a recent stable security update, I get this:

fatal: detected dubious ownership in repository at '/home/ian/Rustup/Arti/arti'
To add an exception for this directory, call:
git config --global --add safe.directory /home/ian/Rustup/Arti/arti

I understand the reason for this. However, my tool deliberately
arranges to trust a repository owned by a different user: indeed, it
is about to execute code from that user's directory. The build user
trusts (must trust) the source code user, so this is fine.

So I would like to pass
-c safe.directory=*

However

This config setting is only respected when specified in a system or
global config, not when it is specified in a repository config or
via the command line option -c

This is preventing me from disabling this check. I don't understand
why we wouldn't trust the command line.

Ian.
