  $ hg topic foo
  marked working directory as topic: foo
  $ mkcommit ccc
  active topic 'foo' grew its first changeset

  $ mkcommit eee
  $ mkcommit fff
  $ hg topic bar
  $ mkcommit ggg

  $ hg next
  no children on topic "foo"
  do you want --no-topic
  [1]
  $ hg next --no-topic
  switching to topic bar
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [14] add ggg
