We only show progress when there are new objects to be packed. But
when --keep-pack is specified on the base pack, we will exclude most
of objects. This makes 'pack-objects' stay silent for a long time
while the counting phase is going.

Let's show some progress whenever we visit an object instead. The
number of packed objects will be shown after if it's not the same as
the number of visited objects.

Since the meaning of this number has changed, use another word instead
of "Counting" to hint about the change.

Can you elaborate on how the meaning has changed? With/without this on
linux.git I get:

With:

    Enumerating objects: 5901144, done.
    Getting object details: 100% (5901145/5901145), done.
    Delta compression using up to 8 threads.

Without:

    Counting objects: 5901145, done.
    Delta compression using up to 8 threads.

So now we're seemingly off-by-one but otherwise doing the same thing?

As for as user feedback goes we might as well have said "Reticulating
splines", but I have some bias towards keeping the current "Counting
objects..." phrasing. We ourselves have other docs referring to it that
aren't changed by this patch, and there's
e.g. https://githubengineering.com/counting-objects/ and lots of other
3rd party docs that refer to this.
