+#
+# This test covers 2 cases in subtree split copy_or_skip code
+# 1) Merges where one parent is a superset of the changes of the other
+# parent regarding changes to the subtree, in this case the merge
+# commit should be copied
+# 2) Merges where only one parent operate on the subtree, and the merge
+# commit should be skipped
+#
+# (1) is checked by ensuring subtree_tip is a descendent of subtree_branch
+# (2) should have a check added (not_a_subtree_change shouldn't be present
+# on the produced subtree)
+#
+# Other related cases which are not tested (or currently handled correctly)
+# - Case (1) where there are more than 2 parents, it will sometimes correctly copy
+# the merge, and sometimes not
+# - Merge commit where both parents have same tree as the merge, currently
+# will always be skipped, even if they reached that state via different
+# set of commits.
