+Tests the resolution of public content divergence: when merging leads to public

+This file intend to cover all the cases possible when merging the other
+divergent cset into public cset leads to public cset itself.
+Possible variants are:
+
+parent: same/different
+relocation: [no-]conflict
+merging: [no-]conflict
