вывод информации по каждому исх (Output information on each ref)
Предостережение (Caveat)
Note that the sizes of objects on disk are reported accurately,
but care should be taken in drawing conclusions about which refs
or objects are responsible for disk usage. The size of a packed
non-delta object may be much larger than the size of objects
which delta against it, but the choice of which object is the
base and which is the delta is arbitrary and is subject to change
during a repack.
Note also that multiple copies of an object may be present in the
object database; in this case, it is undefined which copy's size
or delta base will be reported.
