// Ref is a repository-based baseline method for getting refs. The

// This will attempt to open the file pointed to by the spec. If this
// file is unavailable, packed refs are loaded into memory (and cached)
// and it attempts to find the ref there.
//
// For smart disambiguation of refs, or ref peeling, thou shalt
// use helper operations.
