+# files_subtree/ and master4 as well as files_subtree/master5 add files to that
+# directory directly.
+#
+# Then, in subsequent test cases, `git filter-branch` is used to distill just
+# the commits that touch files_subtree/. To give it a final pre-rebase touch,
+# an empty commit is added on top. The pre-rebase commit history looks like
+# this:
+#
+# Add subproject master - master4 - files_subtree/master5 - Empty commit
+#
+# where the root commit adds three files: master1.t, master2.t and master3.t.
