+====================================
+Testing head checking code: Case E-2
+====================================
+
+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 F: case involving changeset on multiple branch
+TestCase 2: moving interleaved branch away from each other

+.. old-state:
+..
+.. * 2-changeset on branch default
+.. * 1-changeset on topic Z (between the two other)
+..
+.. new-state:

+.. * 2-changeset on branch default, aligned
+.. * 1-changeset on topic Z (at the same location)

+Test setup
+----------
+
+  $ mkdir E1
+  $ cd E1
+  $ setuprepos
+  creating basic server and client repo
+  updating to branch default
+  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
+  $ cd client
+  $ hg topic Z
+  marked working directory as topic: Z
+  $ mkcommit B0
+  active topic 'Z' grew its first changeset
+  (see 'hg help topics' for more information)
+  $ hg topic --clear
+  $ mkcommit C0
+  created new head
+  (consider using topic for lightweight branches. See 'hg help topic')
+  $ hg push
+  pushing to $TESTTMP/E1/server
+  searching for changes
+  adding changesets
+  adding manifests
+  adding file changes
+  added 2 changesets with 2 changes to 2 files
+  $ hg up 0
+  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
+  $ mkcommit A1
+  created new head
