Test NGTip feature

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

Simple linear case

  $ echo babar >> jungle

  $ hg add jungle

  $ hg ci -t elephant -m babar

  $ hg log -G

  @  4 (elephant) babar

  o  2 () c_gamma

  |

  o  1 () c_beta

  |

  o  0 () c_alpha

  $ hg log -r 'ngtip(.)'

  3 () c_delta

multiple heads with topic

  $ hg up "desc('c_beta')"

  0 files updated, 0 files merged, 3 files removed, 0 files unresolved

  $ echo zephir >> jungle

  $ hg add jungle

  $ hg ci -t monkey -m zephir

  created new head

  $ hg log -G

  @  5 (monkey) zephir

  o  0 () c_alpha

  $ hg log -r 'ngtip(.)'

one of the head is a valid tip

  $ hg up "desc('c_delta')"

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

  $ echo epsilon >> epsilon

  $ hg add epsilon

  $ hg ci -m "c_epsilon"

  created new head
