From: SZEDER Gábor <szeder.dev@xxxxxxxxx>
The commit graph file format describes an optional 'Large Edge List'
chunk, and the function writing out this chunk is called
write_graph_chunk_large_edges(). Then there are two functions in
'commit-graph.c', namely write_graph_chunk_data() and
write_commit_graph(), which have a local variable called
'num_extra_edges'.
It can be confusing on first sight whether large edges and extra edges
refer to the same thing or not, but they do, so let's rename those
variables to 'num_large_edges'.
