The storage model does not - it is not file-delta based, like SVN and Mercurial. However, you as a developer can (and often do) think of the commits in terms of a changeset or "work introduced" - this is evident in tools that exist like 'rebase' which treats each commit in a branch as a patch and the collection of unique commits on that branch as a patch series and helps you transfer that series elsewhere. The 'cherry-pick' command is similar - it enforces your thinking of each commit as a changeset or patch to what came before it.
