evolve: add test to demonstrate issue6203
Current logic of content-divergence resolution contains a bug that
if resolution parent is not the parent of any of the two divergent
changesets, it could undo some changes.
I think a good solution for this is to first relocate the divergent cset
to it's obsolete parent's successor if applicable and then perform
the content-divergence resolution.
Next patch will fix the issue.
=============================================================
Tests the resolution of public content divergence: main cases
=============================================================
This file intend to cover all the common cases of public content divergence.
That is all the variant of:
parent: same/different
relocation: [no-]conflict
merging: [no-]conflict
