Testing head checking code: Case D-2

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

Mercurial checks for the introduction of multiple heads on push. Evolution

comes into play to detect if existing heads on the server are being replaced by

some of the new heads we push.

This test file is part of a series of tests checking this behavior.

Category D: remote head is "obs-affected" locally, but result is not part of the push.

TestCase 1: remote branch has 2 changes, head is pruned, second is rewritten but result is not pushed

.. old-state:

..

.. * 1 changeset branch

..

.. new-state:

..

.. * old head is pruned

.. * 1 new branch succeeding to the other changeset in the old branch

.. * 1 new unrelated branch

..

.. expected-result:

..

.. * push allowed

.. * pushing only the unrelated branch: denied
