Testing head checking code: Case C-3

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

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 C: checking 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
