    attr: cache nonexistent attr files from commits
    
    When looking up an attribute file in a commit, we can cache a
    nonexistent attribute file indefinitely (since a commit could not
    somehow later contain an attribute file).  Cache an empty buffer when an
    attribute file does not exist in a given commit.
