Testing head checking code: Case D-7

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

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 D: remote head is "obs-affected" locally, but result is not part of the push

TestCase 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset

This is a partial push variation of B6

.. old-state:

..

.. * 1 changeset branch

..

.. new-state:

..

.. * old branch is rewritten onto another one,

.. * The rewriting it again rewritten on the root

.. * the new version is then pruned.

..

.. expected-result:

..

.. * push allowed
