Tests the resolution of content divergence: basic cases

This file intend to cover basic case of content divergence. See the other test

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

  changed branch on 1 changesets

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

  updated to hidden changeset c41c793e0ef1

  (hidden revision 'c41c793e0ef1' was rewritten as: 9e5dffcb3d48)

  working directory parent is obsolete! (c41c793e0ef1)

  (use 'hg evolve' to update to its successor: 9e5dffcb3d48)

  $ echo bar > d

  $ hg branch watwat
