Auto-detect repositories

Discovery might be a performance-issue when navigating deep hierarchies, as in when the user is navigating D:\dir1\dir2\dir3\...\dir99, especially over high-latency interfaces (like network-storage), but it would be neat if by default the system checked if the current directory and parent-directories have a .git directory (or equivalent)

hope this gets added. i'm not going through some windows settings ui manually each time i create a new repo
