It took me several reads to figure out what was going on here, because I
did not see the deleted ref passed to the list of items to delete from
packed_refs. The part I was missing is something like:
The repack_without_ref() function first removes the deleted ref from
the internal packed-refs list, then writes the packed-refs list to
disk, omitting any broken or stale entries. This patch splits that
second step into multiple passes:
...
