Tests next and prev behavior
============================

Basic move are restricted to the current topic

  $ hg up foo
  switching to topic foo
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg prev
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [14] add eee
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [15] add fff
  $ 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
  [16] add ggg
  $ hg prev
  no parent in topic "bar"
  (do you want --no-topic)
  $ hg prev --no-topic
  switching to topic foo
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
