pub fn git_rev_parse(args: &[&str]) -> Option<PathBuf>Expand description
Run git rev-parse with the given arguments and return the output as a path.
Returns None if git is not available, the command fails, or the output is empty.
Strips inherited GIT_* routing vars before spawning so the git
invocation resolves the repository from its own cwd/args, not from
the parent hook or CI environment. See nb-api:issues/3.
