Function resolveRemoteURL

pkg/cli/git.go:154–195

resolveRemoteURL resolves the best git remote URL to use for a given directory. It first tries the 'origin' remote for backward compatibility. If 'origin' is not configured but exactly one other remote exists, that remote is used instead. Returns the remote URL, the remote name used, and any error.
