Testing head checking code: Case C-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 C: case were the branch is only partially obsoleted

TestCase 3: 2 changeset branch, only the head is pruned

.. old-state:

..

.. * 2 changeset branch

..

.. new-state:

..

.. * old head is pruned

.. * 1 new unrelated branch

..

.. expected-result:

..

.. * push denied
