Reverse the effects of an :hg:`amend` operation. Hides the current commit

revert the state of the working copy, so changes that were added to the
commit in the last amend operation become pending changes in the working

:hg:`unamend` cannot be run on amended commits that have children. In
other words, you cannot unamend an amended commit in the middle of a
stack.
.. note::
Running :hg:`unamend` is similar to running :hg:`undo --keep`
immediately after :hg:`amend`. However, unlike :hg:`undo`, which can
only undo an amend if it was the last operation you performed,
:hg:`unamend` can unamend any draft amended commit in the graph that
does not have children.
.. container:: verbose
Although :hg:`unamend` is typically used to reverse the effects of
:hg:`amend`, it actually rolls back the current commit to its previous
version, regardless of whether the changes resulted from an :hg:`amend`
operation or from another operation, such as :hg:`rebase`.

Non-obsolete descendants of pruned changesets become "unstable". Use

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 must acknowledge it by passing ``--split``. Similarly, when you
prune multiple changesets with a single successor, you must pass the
``--fold`` option.
