The change below over-counts the number of commits we are processing (by 
at least double, possibly triple).

This count is the number of oids given to the method. For 'git 
commit-graph write --reachable', this will be the number of refs.

This is the important count, since we will be parsing commits and adding 
their parents to the list. The bulk of the work happens here.

This iterates through the commits a second time and removes the 
UNINTERESTING flag.

I think it is good to have the progress start before the first loop and 
end after the third loop, but the middle loop has the important count.

I tried deleting the first and third display_progress() methods and 
re-ran the process on the Linux repo and did not notice a delay at the 
0% and 100% progress spots. The count matches the number of commits.

Thanks,
