Orphan changeset and trying to relocate a node on top of itself (issue6097)
https://bz.mercurial-scm.org/show_bug.cgi?id=6097

  $ . $TESTDIR/testlib/common.sh

  $ cat << EOF >> $HGRCPATH

  > EOF

  $ hg init issue6097
  $ cd issue6097

  $ echo apricot > a
  $ hg ci -qAm apricot

  $ echo banana > b
  $ hg ci -qAm banana

Let's go back to amend 0 and make an orphan out of 1

  $ hg up -q 0
  $ echo coconut > c
  $ hg add -q c
  $ hg ci --amend -m 'apricot and coconut'
  1 new orphan changesets

Now rebase the successor of 0 on top of 1

  $ hg rebase -r . -d 1
  rebasing 2:32acf8fb1b23 tip "apricot and coconut"
  1 new orphan changesets

Pruning 1 just to get it out of the way

  $ hg prune -q 1

Note how both the regular DAG and the obsolescence graph are linear, but the
paths from 3 to 0 are different: 3-1-0 and 3-2-0
