The ability to "...fatten [the] local repository by packing everything that is needed by the local ref into a single new pack, including things that are borrowed from alternates"[1] is supposed to be provided by the '-a' or '-A' options to repack when '-l' is not used, but there is a flaw. For each pack in the local repository without a .keep file, repack supplies a --unpacked=<pack> argument to pack-objects. The --unpacked option to pack-objects, with or without an argument, causes pack-objects to ignore any object which is packed in a pack not mentioned in an argument to --unpacked=. So, if there are local packs, and 'repack -a' is called, then any objects which reside in packs accessible through alternates will _not_ be packed. If there are no local packs, then no --unpacked argument will be supplied, and repack will behave as expected.
