+====================================
+Testing head checking code: Case B-5
+====================================
+
+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 5: multi-changeset branch, mix of pruned and superceeded

+.. * 3 changeset branch
+..
+.. new-state:
+..
+.. * old head is pruned
+.. * old mid is superceeded
+.. * old root is pruned

+.. expected-result:

+.. * push allowed
