Testing head checking code: Case B-5

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

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 B: checking simple case involving pruned changesets

TestCase 5: multi-changeset branch, mix of pruned and superceeded

.. old-state:

..

.. * 3 changeset branch

..

.. new-state:

..

.. * old head is pruned

.. * old mid is superceeded

.. * old root is pruned

..

.. expected-result:

..

.. * push allowed
