Reverse the effects of an :hg:`amend` operation. Hides the current commit
and checks out the previous version of the commit. :hg:`unamend` does not
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

.. 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`.
