Check the help
  $ hg amend -h
  hg amend [OPTION]... [FILE]...
  
  aliases: refresh
  
  combine a changeset with updates and replace it with a new one
  
      Commits a new changeset incorporating both the changes to the given files
      and all the changes from the current parent changeset into the repository.
  
      See 'hg commit' for details about committing changes.
  
      If you don't specify -m, the parent's message will be reused.
  
      If --extract is specified, the behavior of 'hg amend' is reversed: Changes
      to selected files in the checked out revision appear again as uncommitted
      changed in the working directory.
  
      Returns 0 on success, 1 if nothing changed.
  
  options ([+] can be repeated):
  
   -A --addremove           mark new/missing files as added/removed before
                            committing
   -a --all                 match all files
   -e --edit                invoke editor on commit messages
      --extract             extract changes from the commit to the working copy
      --patch               make changes to wdir parent by editing patch
      --close-branch        mark a branch as closed, hiding it from the branch
                            list
   -s --secret              use the secret phase for committing
   -n --note TEXT           store a note on amend
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
   -m --message TEXT        use text as commit message
   -l --logfile FILE        read commit message from file
   -d --date DATE           record the specified date as commit date
   -u --user USER           record the specified user as committer
   -D --current-date        record the current date as commit date
   -U --current-user        record the current user as committer
   -i --interactive         use interactive mode
  
  (some details hidden, use --verbose to show complete help)

Check that we abort if --patch and --extract both are used at once
  $ hg amend --patch --extract
  abort: cannot use both --patch and --extract

Check the pre-check logic for content-divergence

  updated to hidden changeset 9092f1db7931
  (hidden revision '9092f1db7931' was rewritten as: aafaf407b00d)
  working directory parent is obsolete! (9092f1db7931)

when rewritting an already rewritten changeset (i.e cset being rewritten will
be the base of divergence)
  $ hg amend -m "i am gonna create divergence"
  abort: cannot amend 9092f1db7931, as that creates content-divergence with aafaf407b00d

  $ hg amend -m "i am gonna create divergence" --verbose
  abort: cannot amend 9092f1db7931, as that creates content-divergence with aafaf407b00d
      changeset 9092f1db7931 already has a successor in changeset aafaf407b00d
      rewriting changeset 9092f1db7931 would create "content-divergence"

when rewritting a cset which has a predecessor with non-obsolete successor

to prepare the repo
1) create content-divergence
2) remove divergence by pruning one of the divergent cset
  $ echo edited_a > a

  $ hg debugobsolete $(hg id -ir 0 --debug) $(hg id -ir 2 --debug)

remove divergence by pruning one side of divergenence
  $ hg debugobsolete $(hg id -ir 2 --debug)
  1 new obsolescence markers
  obsoleted 1 changesets
