The only caller that passes a non-zero value to prepare_revision_walk
after this patch is builtin/pack-objects. Without this, sparsity seems
to do little good therein, as prepare_revision_walk will densely
propagate UNINTERESTING flags from trees to tree contents, before
mark_edges_uninteresting has a chance to be faster by being sparse.
