When you prune the parent of your working copy, Mercurial updates the working
copy to a non-obsolete parent.
You can use ``--succ`` to tell Mercurial that a newer version (successor) of the
pruned changeset exists. Mercurial records successor revisions in obsolescence
markers.
You can use the ``--biject`` option to specify a 1-1 mapping (bijection) between
revisions to pruned (precursor) and successor changesets. This option may be
removed in a future release (with the functionality provided automatically).
If you specify multiple revisions in ``--succ``, you are recording a "split" and
