Hi,

as reported by Waleed in [1], the reference-transaction hook is being
executed when packing refs. Given that the hook ideally ought to track
logical updates to refs instead of leaking low-level implementation
details of how the files backend works, this is understandably leading
to some confusion.

This patch series aims to fix that by improving how the tandom of loose
and packed refs backends interact such that we skip executing the hook
when the loose backend:

    - repacks references.
    - needs to delete packed refs when deleting a loose ref would
      uncover that packed ref.

Patrick
