It looks like this test is failing due to a behavior change in borgmatic:

==> /opt/homebrew/Cellar/borgmatic/1.6.1/bin/borgmatic -v 2 --config /private/tmp/borgmatic-test-20220530-96174-w431n3/config.yml --init --encryption repokey

  /private/tmp/borgmatic-test-20220530-96174-w431n3/config.yml: Error getting local Borg version

  Could not parse Borg version string

Specifically, this commit where it's now checking for a version of borg, in order to decide to execute the compact command or not.

I believe the fix would be to update the borg stub in the test.

For example, borg --version returns borg 1.2.0
