+====================================
+Testing head checking code: Case C-4
+====================================
+
+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 C: case were the branch is only partially obsoleted
+TestCase 4: 2 changeset branch, only the base is pruned
+
+.. old-state:
+..
+.. * 2 changeset branch
+..
+.. new-state:
+..
+.. * old base is pruned
+.. * 1 new unrelated branch
+..
+.. expected-result:
+..
+.. * push denied
