Merge branch 'ab/commit-graph-write-progress'
The codepath to show progress meter while writing out commit-graph
file has been improved.
* ab/commit-graph-write-progress:
commit-graph write: emit a percentage for all progress
commit-graph write: add itermediate progress
commit-graph write: remove empty line for readability
commit-graph write: add more descriptive progress output
commit-graph write: show progress for object search
commit-graph write: more descriptive "writing out" output
commit-graph write: add "Writing out" progress output
commit-graph: don't call write_graph_chunk_extra_edges() unnecessarily
commit-graph: rename "large edges" to "extra edges"
