Call Git::command() and friends directly wherever possible.
This makes it clear that these operations can be invoked directly
without needing to manage the current directory and related GIT_*
environment variables.
Eliminate find_repository() since we can now use wc_path() and
not worry about side-effects involving environment variables.
