Merge branch 'cb/path-owner-check-with-sudo-plus'

"sudo git foo" used to consider a repository owned by the original
user a safe one to access; it now also considers a repository owned
by root a safe one, too (after all, if an attacker can craft a
malicious repository owned by root, the box is 0wned already).

* cb/path-owner-check-with-sudo-plus:
  git-compat-util: allow root to access both SUDO_UID and root owned
