Please follow Documentation/SubmittingPatches.  This should be part of
the actual email headers. And there should be one patch per email.

My first thought was "doesn't git-repack already show progress?".
There's no motivation in the commit message, so I have to guess why you
want this. I assume you want to override the isatty(2) decision that
pack-objects uses?

Should this also handle --no-progress? Maybe it is not a big deal, as
"-q" will also suppress progress, but it would be consistent with other
git commands that take --progress.

This just seems redundant to me.

Though this is a nice description.

This will handle --no-progress for us automatically, which is good.

This won't, but I think this whole hunk is unnecessary. The files in
contrib/examples are kept around for people to see how git commands can
be composed of plumbing building blocks. But they don't need to gain new
features as their C counterparts do. I think we can just leave them
frozen in time as of when each script was rewritten in C.
