Tests the resolution of content divergence: basic cases

This file intend to cover basic case of content divergence. See the other test
file for more advanced cases.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once

Merging branch difference
-------------------------

Creating content-divergence with branch change where base, divergent and other
have different branches

  $ hg branch -r . foobar
  changed branch on 1 changesets

  $ hg up c41c793e0ef1 --hidden
  updating to a hidden changeset c41c793e0ef1
  (hidden revision 'c41c793e0ef1' was rewritten as: 9e5dffcb3d48)
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory parent is obsolete! (c41c793e0ef1)
  (use 'hg evolve' to update to its successor: 9e5dffcb3d48)
  $ echo bar > d
  $ hg branch watwat
  marked working directory as branch watwat
  $ hg amend
  2 new content-divergent changesets

has different one

  $ echo bar > d
  $ hg ci -Aqm "added a d with bar in it, expect some beers"
