From: Lessley Dennington <redacted> Check whether git dir exists before adding any repo settings. If it does not exist, BUG with the message that one cannot add settings for an uninitialized repository. If it does exist, proceed with adding repo settings. Additionally, ensure the above BUG is not triggered when users pass the -h flag by adding a check for the repository to the checkout and pack-objects builtins. Finally, ensure the above BUG is not triggered for commit-graph by returning early if the git directory does not exist.
