Also test the revset:

  $ hg log -r 'stack()'

Case with multiple heads on the topic

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

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'

  rebasing 4:4f2a69f6d380 "c_e"

  rebasing 5:913c298d8b0a "c_f"

  $ hg log -G

  o  9 foo {} draft c_f

  o  8 foo {} draft c_e

  @  7 foo {} draft c_d

  |

  o  2 foo {} draft c_c

  |

  o  1 other {} public c_b

  |

  o  0 other {} public c_a

Create the second branch

  $ hg up 'desc(c_d)'

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

  $ echo aaa > ggg

  $ hg add ggg

  $ hg commit -m c_g

  created new head

  $ echo aaa > hhh

  $ hg add hhh

  $ hg commit -m c_h

  $ hg log -G

  @  11 foo {} draft c_h
