divergence-resolution: add a buggy test case for resolution

Explained in more details in the test itself. This will be fixed
by next patch.

+===============================================
+Testing content-divergence resolution: Case A.5
+===============================================
+
+Independent rewrites of same changeset can lead to content-divergence. In most
+common cases, it can occur when multiple users rewrite the same changeset
+independently and push it.
+
+This test belongs to a series of tests checking the resolution of content-divergent
+changesets.
+
+Category A: no parents are obsolete
+Testcase 5: one side relocated backward and other rebased to parent's successor
+Variants:
+# a: "local" is relocated backward
+# b: "other" is relocated backward
+
+A.5 Relocated backward; Rebased to parent's successor
+=====================================================
+
+.. (Divergence reason):
+..    local: relocated the changeset backward in the graph
+..    other: rebased to the successor of parent
+.. Since one side rebased to the successor of parent and other cset relocated backward,
+.. the most reasonable behaviour is to set the parent of "backward-relocated" cset
+.. as resolution parent of divergence.
