Add more progress output to the output already added in
7b0f229222 ("commit-graph write: add progress output", 2018-09-17).
As noted in that commit most of the progress output isn't displayed on
small repositories, but before this change we'd noticeably hang for
2-3 seconds at the end on medium sized repositories such as linux.git.
Now we'll instead show output like this, and have no human-observable
point at which we're not producing progress output:
$ ~/g/git/git --exec-path=$HOME/g/git commit-graph write
Finding commits for commit graph: 6418991, done.
Computing commit graph generation numbers: 100% (797205/797205), done.
Writing out commit graph chunks: 2399861, done.
This "graph chunks" number is not meant to be meaningful to the user,
but just to show that we're doing work and the command isn't
hanging.
On a much larger in-house repository I have we'll show (note how we
also say "Annotating[...]"):
$ ~/g/git/git --exec-path=$HOME/g/git commit-graph write
Finding commits for commit graph: 48271163, done.
Annotating commit graph: 21424536, done.
Computing commit graph generation numbers: 100% (7141512/7141512), done.
Writing out commit graph chunks: 21424913, done.
