Add the '--points-at' option provided by 'ref-filter'. The
option lets the user to list only refs which pertain to the
given object.
You are using "pertain to" (here, in git-for-each-ref.txt and in the
docstring), while the common use it to talk about "point to" or "point
at". I find "point" clearer.
