evolve: handle a case in pubic-div when merging results in same as public
In public divergence resolution, what we do is:
1) first apply content divergence resolution
2) then phase divergent resolution on resultant node of 1) case
While doing case 1 it is possible that result of merging the two csets
would have same changes as public one contains. And then processing
the case 2 would create an empty commit which is not something we want
to do.
So this patch catch that same case when merging results in same as public
cset and don't create a new node, instead to solve the divergence
it just add a obsmarker from "other divergent" to "public divergent"
i.e. [other, (public,)]
Next patch will add the continue case handling for this same case.
This patch also adds the tests for the different cases which are possible
for the above mentioned case.
There is test for continue case too which is broken in this patch
and will be fixed in next patch.
============================================
Testing obsolescence markers push: Cases B.7
============================================
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 B: pruning case
TestCase 7: Prune on non-targeted common changeset
B.7 Prune above non-targeted common changeset
=============================================
.. (very similar to B1, but the prune changeset is unknown on remote)

.. Marker exist from:

.. Command runs:
