Hmm... I should read manpages more often! :)

So, do you suggest that this is a better approach:

- mother repos: "git repack -adk"
- child repos: "git repack -Adl" (followed by prune)

Currently, we do "-Adl" regardless, but we already track whether a repo
is being used for alternates anywhere (so we don't prune it) and can do
different flags if that improves performance.

Best,
