Summary

Last patch introduced config reading at startup to parse value of --repository
flag. However, that patch only tried to check for current repository at current
working directory and not it's ancestors. This patch fixes that.

This doc should also mention ancestors. Something like "Find the nearest repository root, if any, in the current directory or its ancestors"

The try_ prefix can be dropped from the name since fallibility is already apparent from the return type and there’s no equivalent infallibly (panicky) API. Compare with std::cell::RefCell which has both borrow and try_borrow, and std::fs::File whose open method is not named try_open.

Please use if let or match instead of is_ok + unwrap

Sorry I didn’t realize this earlier: this entire match can be replaced with the ? operator:

let root = Self::find_repo_root()?
Self::new_at_path(root, config)
