Merge lp:~thomir/bzr-bisect/fix-for-quantal into lp:bzr-bisect

[Thomi Richards]

Update to use 'graph.iter_lefthand_ancestry' instead of 'repo.iter_reverse_revision_history' making bzr-bisect compatible with bzr 2.6b2

lp:bzr-bisect still uses 'repo.iter_reverse_revision_history', which has been removed from bzrlib. This branch changes that code to use 'graph.iter_lefthand_ancestry' instead.

Can you land this, or should I?
