Testing when relocation results in nothing to commit
----------------------------------------------------

Set up a repo where relocation results in no changes to commit because the
changes from the relocated node are already in the destination.

  $ hg init nothing-to-commit
  $ cd nothing-to-commit
  $ echo 0 > a
  $ hg ci -Aqm initial
  $ echo 1 > a
  $ hg ci -Aqm upstream
  $ hg prev -q

Create the source of divergence.
  $ echo 0 > b
  $ hg ci -Aqm divergent

The first side of the divergence get rebased on top of upstream.
  $ hg rebase -r . -d 'desc("upstream")'
  rebasing 2:898ddd4443b3 "divergent" (tip)
  $ hg --hidden co 2 -q
  updated to hidden changeset 898ddd4443b3
  (hidden revision '898ddd4443b3' was rewritten as: befae6138569)
  working directory parent is obsolete! (898ddd4443b3)

The other side of the divergence gets amended so it matches upstream.
Relocation (onto upstream) will therefore result in no changes to commit.
  $ hg revert -r 'desc("upstream")' --all
  removing b
  reverting a
  $ hg amend --config experimental.evolution.allowdivergence=True
  2 new content-divergent changesets

Add a commit on top. This one should become an orphan. Evolving it later
