Make some commits:

  $ for i in 1 2 3; do
  >   echo $i >> a
  >   hg commit -A a -m "commit $i" -q
  > done

absorb --edit-lines will run the editor if filename is provided:

  $ hg absorb --edit-lines --apply-changes

  $ HGEDITOR=cat hg absorb --edit-lines --apply-changes a
  HG: editing a
  HG: "y" means the line to the right exists in the changeset to the top
