commit-graph: split up close_reachable() progress output
Amend the progress output added in 7b0f229222
("commit-graph write:
add progress output", 2018-09-17) so that the total numbers it reports
aren't higher than the total number of commits anymore. See [1] for a
bug report pointing that out.
When I added this I wasn't intending to provide an accurate count, but
just have some progress output to show the user the command wasn't
hanging[2]. But since we are showing numbers, let's make them
accurate. The progress descriptions were suggested by Derrick Stolee
in [3].
As noted in [2] we are unlikely to show anything except the "Expanding
reachable..." message even on fairly large repositories such as
linux.git. On a test repository I have with north of 7 million commits
all of these are displayed. Two of them don't show up for long, but as
noted in [5] future-proofing this for if the loops become more
expensive in the future makes sense.
