Test for handling of content divergence with public cset using `hg evolve`
==========================================================================
Setup

$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
Testing the case when both divergent cset are on the same parent and no-conflict in merging:
-------------------------------------------------------------------------------------
Prepare the repository:
$ hg init pubdiv
$ cd pubdiv
$ for ch in a b; do
> echo $ch > $ch;
> hg ci -Aqm "added "$ch;
> done;
$ hg glog
@ 1:5f6d8a4bf34a added b

Make an amend and change phase to public:
$ sed -i "1 i I am first" b
$ hg amend
$ hg phase --public
Amend again to create a cset divergent to public one:
$ hg up 1 --hidden -q

merging "other" content-divergent changeset '44f360db368f'
merging b

On server side: a new cset is added based on rev 1 and rev 2 is rebased on newly added cset:
$ hg up .^ -q
$ echo d > d

created new head
$ hg rebase -r 2 -d .
