Pruned changesets are obsolete with no successors. If they also have no

Non-obsolete descendants of pruned changesets become "unstable". Use
:hg:`evolve` to handle this situation.
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.

Replaces your current commit with a new commit that contains the contents

By default, all pending changes (in other words, those reported by 'hg
status') are committed. To commit only some of your changes,
you can:
- Specify an exact list of files for which you want changes committed.
- Use the -I or -X flags to pattern match file names to exclude or
include by using a fileset. See 'hg help filesets' for more
information.
- Specify the --interactive flag to open a UI that will enable you
to select individual insertions or deletions.
By default, hg amend reuses your existing commit message and does not
prompt you for changes. To change your commit message, you can:
- Specify --edit / -e to open your configured editor to update the
existing commit message.
- Specify --message / -m to replace the entire commit message, including
any commit template fields, with a string that you specify.
.. note::
Specifying -m overwrites all information in the commit message,
including information specified as part of a pre-loaded commit
template. For example, any information associating this commit with
a code review system will be lost and might result in breakages.
When you amend a commit that has descendants, those descendants are
rebased on top of the amended version of the commit, unless doing so
would result in merge conflicts. If this happens, run 'hg restack'
to manually trigger the rebase so that you can go through the merge
conflict resolution process.
