+Testing head checking code: Case C-3
+====================================
+
+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 C: checking case were the branch is only partially obsoleted.
+TestCase 3: 2 changeset branch, only the head is pruned
+
+.. old-state:

+.. * 2 changeset branch
+..
+.. new-state:
+..
+.. * old head is pruned
+.. * 1 new unrelated branch
