Best way to check if repo has any remote commits?

[rnag]

Currently i have been using :

// Check the remote commit history for a Git repository
func repoHasRemoteCommits(r *git.Repository) bool {
	var hasRemoteCommits bool
	revision := "origin/master"

	_, err := r.ResolveRevision(plumbing.Revision(revision))
	hasRemoteCommits = err == nil

	return hasRemoteCommits
}

Does this approach cover all edge cases? wondering if there is a better way as well.
