stack: display the base of the stack

Displaying the first parent of the stack seems useful. I'm even tempted to call
it 't0' and have the topic still active when 'hg up t0' is used to move to the
base.

As a side effect we gain a way to denote that the stack is not linear. I'm not
super convinced that it is the right way to display it, but this is better than
no information.

Initial setup


  $ cat << EOF >> $HGRCPATH
  > [ui]
  > logtemplate = {rev} {branch} \{{get(namespaces, "topics")}} {phase} {desc|firstline}\n
  > [experimental]
  > evolution=createmarkers,exchange,allowunstable
  > EOF

(new head warning seems buggy)
  $ hg init main
  $ cd main
  $ echo aaa > aaa
  $ hg add aaa
  $ hg commit -m c_a
  $ echo aaa > bbb
  $ hg add bbb
  $ hg commit -m c_b
  $ hg topic foo
  $ echo aaa > ccc
  $ hg add ccc
  $ hg commit -m c_c
  $ echo aaa > ddd
  $ hg add ddd
  $ hg commit -m c_d
  created new head
  $ echo aaa > eee
  $ hg add eee
  $ hg commit -m c_e
  created new head
  $ echo aaa > fff
  $ hg add fff
  $ hg commit -m c_f
  created new head
  $ hg log -G
  @  5 default {foo} draft c_f
  |
  o  4 default {foo} draft c_e
  |
  o  3 default {foo} draft c_d

  o  2 default {foo} draft c_c

  o  1 default {} draft c_b

  o  0 default {} draft c_a
  

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

hg topic -l list all changeset in the topic

  $ hg topic
   * foo
  $ hg topic --list
    _ c_b
  t0: c_c
  t1: c_d
  t2: c_e
  t3@ c_f (current)

error case, nothing to list

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

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


  $ hg up t1
  abort: cannot resolve "t1": no active topic
  [255]
  $ hg topic foo
  $ hg up t42
  abort: cannot resolve "t42": topic "foo" has only 4 changesets
  [255]
  $ hg up t1
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved

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 {} draft c_b
  |
  o  0 default {} draft c_a
  
  $ hg topic --list
    _ c_b
  t0: c_c
  t1@ c_d (current)
  t2$ c_e (unstable)
  t3$ c_f (unstable)

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

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
  rebasing 4:91fa8808d101 "c_e"
  rebasing 5:4ec5094907b7 "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 {} draft c_b
  |
  o  0 default {} draft 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
  created new head
  $ 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 {} draft c_b
  |
  o  0 default {} draft c_a
  

Test output

  $ hg top -l
    _ c_b
  t0: c_c
  t1: c_d
  t2: c_g
  t3@ c_h (current)
    _ c_d
  t4: c_e
  t5: c_f

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 10:11286b4fcb3d "c_g"
  rebasing 11:3ad57527186d "c_h"
  $ hg log -G
  o  15 default {foo} draft c_h
  |
  o  14 default {foo} draft c_g
  |
  @  13 default {foo} draft c_D
  |
  | o  9 default {foo} draft c_f
  | |
  | o  8 default {foo} draft c_e
  | |
  | x  7 default {foo} draft c_d
  |/
  o  2 default {foo} draft c_c
  |
  o  1 default {} draft c_b
  |
  o  0 default {} draft c_a
  

  $ hg topic --list
