stack: reusing the index number in base when applicable

This clarify the branching when it is easy to track back the branching point.

This does not takes the evolution graph into account yet.

Check that topic without any parent does not crash --list
---------------------------------------------------------

  $ hg up other
  switching to topic other
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg topic --list
  t2@ c_b (current)
  t1: c_a
  $ hg phase --public 'topic("other")'
  $ hg up foo
  switching to topic foo
  4 files updated, 0 files merged, 0 files removed, 0 files unresolved

Simple test
-----------

'hg stack' list all changeset in the topic

  $ hg topic
   * foo
  $ hg stack
  t4@ c_f (current)
  t3: c_e
  t2: c_d
  t1: c_c
    ^ c_b

error case, nothing to list

  $ hg topic --clear
  $ hg stack
  abort: no active topic to list
  [255]

Test "t#" reference
-------------------


  $ hg up t2
  abort: cannot resolve "t2": no active topic
  [255]
  $ hg topic foo
  $ hg up t42
  abort: cannot resolve "t42": topic "foo" has only 4 changesets
  [255]
  $ hg up t2
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg summary
  parent: 3:e629654d7050 
   c_d
  branch: default
  commit: (clean)
  update: (current)
  phases: 4 draft
  topic:  foo

Case with some of the topic unstable
------------------------------------

  $ echo bbb > ddd
  $ hg commit --amend
  $ hg log -G
  @  7 default {foo} draft c_d
  |
  | o  5 default {foo} draft c_f
  | |
  | o  4 default {foo} draft c_e
  | |
  | x  3 default {foo} draft c_d
  |/
  o  2 default {foo} draft c_c
  |
  o  1 default {} public c_b
  |
  o  0 default {} public c_a
  
  $ hg topic --list
  t4$ c_f (unstable)
  t3$ c_e (unstable)
  t2@ c_d (current)
  t1: c_c
    ^ c_b

Also test the revset:

  $ hg log -r 'stack()'
  2 default {foo} draft c_c
  7 default {foo} draft c_d
  4 default {foo} draft c_e
  5 default {foo} draft c_f

Case with multiple heads on the topic
-------------------------------------

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
  rebasing 4:0f9ac936c87d "c_e"
  rebasing 5:6559e6d93aea "c_f"
  $ hg log -G
  o  9 default {foo} draft c_f
  |
  o  8 default {foo} draft c_e
  |
  @  7 default {foo} draft c_d
  |
  o  2 default {foo} draft c_c
  |
  o  1 default {} public c_b
  |
  o  0 default {} 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
  $ echo aaa > hhh
  $ hg add hhh
  $ hg commit -m c_h
  $ hg log -G
  @  11 default {foo} draft c_h
  |
  o  10 default {foo} draft c_g
  |
  | o  9 default {foo} draft c_f
  | |
  | o  8 default {foo} draft c_e
  |/
  o  7 default {foo} draft c_d
  |
  o  2 default {foo} draft c_c
  |
  o  1 default {} public c_b
  |
  o  0 default {} public c_a
  

Test output

  $ hg top -l
  t6: c_f
  t5: c_e
  t2^ c_d (base)
  t4@ c_h (current)
  t3: c_g
  t2: c_d
  t1: c_c
    ^ c_b

Case with multiple heads on the topic with unstability involved
---------------------------------------------------------------

We amend the message to make sure the display base pick the right changeset

  $ hg up 'desc(c_d)'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo ccc > ddd
  $ hg commit --amend -m 'c_D' 
  $ hg rebase -d . -s 'desc(c_g)'
  rebasing 10:81264ae8a36a "c_g"
  rebasing 11:fde5f5941642 "c_h"
  $ hg log -G
