=========================================
Testing single head enforcement: Case A-1
=========================================
A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.
This case is part of a series of tests checking this behavior.
Category A: Involving obsolescence
TestCase 1: A fully obsolete branch kept visible by another one
.. old-state:
..
.. * 2 changesets on branch default
.. * 2 changesets on branch Z on top of them
..
.. new-state:

.. * 2 changesets on branch Z at the same location
.. * 2 changesets on branch default superseding the other ones
..
.. expected-result:

updating to branch default
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd client
$ mkcommit B0
$ hg branch Z
marked working directory as branch Z
(branches are permanent and global, did you want a bookmark?)
$ mkcommit C0
$ mkcommit D0
$ hg push --new-branch
pushing to $TESTTMP/A1/server
searching for changes

adding manifests
adding file changes
added 3 changesets with 3 changes to 3 files
