It may be illuminating to see which objects were not included within a
given filter. This also demonstrates, since filter-spec "tree:1" is
used, that the 'omitted' list contains all objects which are omitted,
not just the first objects which were omitted - that is, it continues to
dereference omitted trees and commits.
This is part of a tutorial on performing revision walks.
