Testing head checking code: Case A-3

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

Mercurial checks for the introduction of new heads on push. Evolution comes

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

some of the new one we push.

This case is part of a series of tests checking this behavior.

Category A: simple case involving a branch being superceeded by another.

TestCase 3: multi-changeset branch with reordering

Push should be allowed

.. old-state:

..

.. * 2 changeset branch

..

.. new-state:

..

.. * 2 changeset branch succeeding the old one with reordering

..

.. expected-result:

..

.. * push allowed

..

.. graph-summary:
