"git rev-list" learns the "--filter=object:type=<type>" option, which can be used to exclude objects of the given kind from the packfile generated by pack-objects. * ps/rev-list-object-type-filter: rev-list: allow filtering of provided items pack-bitmap: implement combined filter pack-bitmap: implement object type filter list-objects: implement object type filter list-objects: support filtering by tag and commit list-objects: move tag processing into its own function revision: mark commit parents as NOT_USER_GIVEN uploadpack.txt: document implication of `uploadpackfilter.allow`
