Testing head checking code: Case B-2

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

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 B: simple case involving pruned changesets

TestCase 2: multi-changeset branch, head is pruned, rest is superceeded, through other

.. old-state:

..

.. * 2 changeset branch

..

.. new-state:

..

.. * old head is rewritten then pruned

.. * 1 new branch succeeding to the other changeset in the old branch (through another obsolete branch)

..

.. expected-result:

..

.. * push allowed
