There's only one caller of it. I don't think it needs to exist as
a standalone function.

  $ hg histedit 6 --commands - << EOF

Test dropping of changeset on the top of the stack

Nothing is rewritten below, the working directory parent must be change for the
dropped changeset to be hidden.

Changeset reordering
-------------------------------------------

If a secret changeset is put before a draft one, all descendant should be secret.
It seems more important to present the secret phase.

  $ cp -R base reorder
  $ cd reorder
  $ hg histedit -r 'b449568bf7fc' --commands - << EOF
  > pick b449568bf7fc 11 f
  > pick 3a6c53ee7f3d 15 j

  > pick b605fb7503f2 14 i
  > pick 7395e1ff83bd 13 h
  > pick ee118ab9fa44 16 k
  > EOF
  $ hg log -G

Changeset folding
-------------------------------------------

Folding a secret changeset with a draft one turn the result secret (again,
better safe than sorry). Folding between same phase changeset still works

Note that there is a few reordering in this series for more extensive test

  $ cp -R base folding
  $ cd folding
  $ cat >> .hg/hgrc << EOF

  $ hg histedit -r 'b449568bf7fc' --commands - << EOF

  > pick b605fb7503f2 14 i

Check abort behavior
-------------------------------------------

We checks that abort properly clean the repository so the same histedit can be
attempted later.

  $ cp -R base abort
  $ cd abort
  $ hg histedit -r 'b449568bf7fc' --commands - << EOF
