From 8c9c051bef3db0fe267f3fb6a1dab293c5f23b38 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Mon, 15 Apr 2024 13:30:36 +0200 Subject: setup.c: introduce `die_upon_dubious_ownership()` Introduce a new function `die_upon_dubious_ownership()` that uses `ensure_valid_ownership()` to verify whether a repositroy is safe for use, and causes Git to die in case it is not. This function will be used in a subsequent commit.
