test the interaction of the branch cache with obsolete changeset

================================================================

Some corner case have been covered by unrelated test (like rebase ones) this

file meant to gather explicite testing of those.

Setup graph

graph with a single branch

We want some branching and some obsolescence

  $ hg init main-single-branch

  $ mkcommit A_2

  $ hg update 'desc("A_2")' --quiet

  $ mkcommit B_1

  $ mkcommit B_2

  $ mkcommit B_3

  $ mkcommit B_4

  $ hg update 'desc("A_2")' --quiet

  $ mkcommit A_3

  created new head

  $ mkcommit A_4

  $ hg up null --quiet

  $ hg clone --noupdate . ../main-single-branch-pre-ops

  $ hg log -r 'desc("A_1")' -T '{node}' > ../main-single-branch-node_A1
