  # NOTE: At present we do not test that "git lfs track" reports
  #       "already supported" when it finds a pattern in a subdirectory's
  #       .gitattributes file which references a macro attribute in
  #       the top-level .gitattributes file that sets "filter=lfs".
  #       This is because, while "git check-attr" resolves macro references
  #       from a file such as dir/.gitattributes to .gitattributess,
  #       "git lfs track" only resolves macro references as it reads these
  #       files in depth-first order, so unlike Git it does not expand an
  #       "lfs" reference to "filter=lfs" if it appears in dir/.gitattributes.
