Git does not use patches (that's darcs, and the idea is, alas, broken:
nobody has ever figured out a way to make a patch algebra work with
merges).

Git uses snapshots of the entire tree, chained together into a
directed graph of commits over time.

More than that, because a commit includes the sha1sums of its
parents and its tree, and a tree includes the sha1sums of all its
component parts, each commit is a proof that the commit itself
has not been modified and that *neither has its entire history*.
