===============================================================================
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
