Build some basic graph

----------------------

  $ for x in base_a base_b base_c base_d base_e ; do

  >   mkcommit $x

  > done

Add another branch with two heads

  $ hg up 'desc(base_a)'

  0 files updated, 0 files merged, 4 files removed, 0 files unresolved

  $ hg branch lake

  marked working directory as branch lake

  (branches are permanent and global, did you want a bookmark?)

  $ mkcommit lake_a

  $ mkcommit lake_b

  $ hg up 'desc(lake_a)'

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

  $ mkcommit lake_c

  created new head

Add some topics

---------------

A simple topic that need rebasing

  $ hg up 'desc(base_c)'

  2 files updated, 0 files merged, 2 files removed, 0 files unresolved

  $ hg topic baz

  $ mkcommit baz_a

  $ mkcommit baz_b

A simple topic with unstability

  $ hg up 'desc(base_d)'

  1 files updated, 0 files merged, 2 files removed, 0 files unresolved

  $ hg topic fuz

  $ mkcommit fuz_a

  $ mkcommit fuz_b

  $ mkcommit fuz_c

  $ hg up 'desc(fuz_a)'

  0 files updated, 0 files merged, 2 files removed, 0 files unresolved

  $ hg commit --amend --message 'fuz1_a'

A topic with multiple heads

  $ hg up 'desc(base_e)'

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

  $ hg topic bar

  $ mkcommit bar_a

  $ mkcommit bar_b

  $ mkcommit bar_c

  $ hg up 'desc(bar_b)'

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

  $ mkcommit bar_d

  $ mkcommit bar_e

  $ hg up 'desc(bar_d)'

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

  $ hg commit --amend --message 'bar1_d'

topic 'foo' on the multi headed branch

  $ hg up 'desc(lake_a)'

  1 files updated, 0 files merged, 7 files removed, 0 files unresolved

  $ hg topic foo

  $ mkcommit foo_a

  $ mkcommit foo_b
