From: Jeff Hostetler <jeffhost@xxxxxxxxxxxxx>
Teach pack-objects to use the filtering provided by the
traverse_commit_list_filtered() interface to omit unwanted
objects from the resulting packfile.
This feature is intended for partial clone/fetch.
Filtering requires the use of the "--stdout" option.
