copies: detect case when a merge decision overwrite previous data
We now detect and record when a merge case required special logic (eg: thing
that append during the merge, ambiguity leading to picking p1 data, etc) and we
explicitly mark the result as superseding the previous data.
This fixes the family of test we previously added.

Testing obsolescence markers push: Cases D.1
============================================
Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).
This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.
Category D: Partial Information Case
TestCase 1: Pruned changeset based on missing precursor of something not present
Variants:
# a: explicite push
# b: bare push
