Re: [PATCH 1/2] repack: teach --no-prune-packed to skip `git prune-packed`

[Rafael Silva <rafaeloliveira.cs@gmail.com>]

Thanks for reviewing this patch. really appreciate it.

However, in the v2, I decided to drop this in favor of just adding a
trace2 event that emits all the loosened objects. This is to avoid
adding user-visible option just for the sake of testing it.

Thanks for catching the typo and the clarification.

Unfortunately, with the drop of this patch in v2, we no longer refactor
these tests. However, this still might be possible with the trace2 event
information that is now-added in the v2. Of course, if this doesn't
impact or weakens the test in anyway.

Yes, this is an improvement of the test description.
