Make a scratch branch with an initial commit.
  $ hg push -q -r . --to scratch/mybranch --create

Amend the commit a couple of times and push to the scratch branch again
  $ hg amend -m "scratchcommit (amended 1)"
  $ hg amend -m "scratchcommit (amended 2)"
  $ hg push -q -r . --to scratch/mybranch --non-forward-move

Clone the repo again, and pull the scratch branch.
  $ cd ..
  $ hg clone ssh://user@dummy/repo client2 -q
  $ cd client2
  $ hg pull -q -B scratch/mybranch

Amend the commit a couple of times again.

We have the predecessor chain that links all versions of the commits.
This works even though we are missing the third amended version.
