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

  |   draft

  |

  o  0:9092f1db7931 added a

      draft

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

  updated to hidden changeset 5f6d8a4bf34a

  (hidden revision '5f6d8a4bf34a' was rewritten as: 44f360db368f)

  working directory parent is obsolete! (5f6d8a4bf34a)

  $ echo "I am second" >> b

  $ hg ci --amend -m "updated b"

  1 new content-divergent changesets

  $ hg glog

  @  3:dcdaf152280a updated b

Lets resolve the public content-divergence:

  $ hg evolve --content-divergent

  merge:[3] updated b

  with: [2] added b

  base: [1] added b

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

  merging b

  0 files updated, 1 files merged, 0 files removed, 0 files unresolved

  committed as c1aa9cfb6cf8

  working directory is now at c1aa9cfb6cf8

Following graph log shows that it correctly merged the two divergent csets:

  $ hg glog -p
