Indeed. Conceptually, git stores whole file contents for all revisions
in blob objects, but git can store multiple objects (blobs, trees,
commits, signed tags) in pack files. Within a pack file, objects can
be encoded as a reference to another object and a delta.
explains some of the consequences in the context of git gc --aggressive.
(When suggesting the --aggressive option, I assumed that git-fast-import
was used to create the repo.)
