Please make the commit message more self-contained, i.e. describe the
issue this patch fixes in more detail, so readers won't have to follow
links to understand the problem.

In my opinion this is rather one of those "we'll cross that bridge
when (or if ever) we get there" situations.

No, after I managed to "get my numbers straight" I sent another bug
report in

  https://public-inbox.org/git/20181015165447.GH19800@szeder.dev/

but as a reply to your original patch.  Sorry about the confusion.

I'm afraid this patch doesn't address that issue, as it's limited to
close_reachable(), and that issue is related to the progress output in
add_packed_commits().
