Bzzzt; wrong answer.

Think of a future when you can shallowly clone near the tip of
git repository that does not have shell-script git-branch.sh
anymore.  You cannot expect to already have the preimage of the
patch in such a case.  You would still want to be able to revert
the change with "git apply -R".
