I have just discovered that, several years ago, my entire home directory got entangled with a git repository. How do I remove that git repository, without affecting anything else, including other git repositories (which I definitely want to keep) in subfolders of my home directory?
Even more confusingly for me, git log shows a friend's email address (this mess probably happened when I was working on a project they had started), but none of git config --get remote.origin.url, git remote -v, git remote show etc. show anything; and git remote show origin shows an error.
