Testing head checking code: Case D-6

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

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

TestCase 6: single changesets, superseeded 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 new version is then pruned.

.. * push denied
