Merge branch 'nd/fetch-into-shallow' into maint
When there is no sufficient overlap between old and new history during a "git fetch" into a shallow repository, objects that the sending side knows the receiving end has were unnecessarily sent. * nd/fetch-into-shallow: Add testcase for needless objects during a shallow fetch list-objects: mark more commits as edges in mark_edges_uninteresting list-objects: reduce one argument in mark_edges_uninteresting upload-pack: delegate rev walking in shallow fetch to pack-objects shallow: add setup_temporary_shallow() shallow: only add shallow graft points to new shallow file move setup_alternate_shallow and write_shallow_commits to shallow.c
