At the moment, this reverse graph contains an edge from commit A to commit B if and only if A is a parent of B. Thus, the name "children" is appropriate for for this reverse graph. In the next change, we will repurpose the reverse graph to not be directly-adjacent commits in the commit-graph, but instead a more abstract relationship. The previous changes have already incorporated the necessary updates to fill_bitmap_commit() that allow these edges to not be immediate children.
