prune: update to the successor of wdir also with --pair/--biject (issue6142)
When prune is used with --pair flag, we can also update to the successor of
working directory parent.
No need to check len(sucs) or len(precs) here because there's a check for that
earlier in the code (it's a requirement of biject).
The tests are now demonstrate the correct behavior: when rev 14 was pruned with
12 as its successor, the bookmark that was on 14 was moved to 12. That bookmark
was also activated (even before this patch).

topic extension - support for topic branches
Topic branches are lightweight branches which disappear when changes are
finalized (move to the public phase).
Compared to bookmark, topic is reference carried by each changesets of the
series instead of just the single head revision. Topic are quite similar to
the way named branch work, except they eventually fade away when the changeset
becomes part of the immutable history. Changeset can belong to both a topic
and a named branch, but as long as it is mutable, its topic identity will
prevail. As a result, default destination for 'update', 'merge', etc... will
take topic into account. When a topic is active these operations will only
consider other changesets on that topic (and, in some occurrence, bare
changeset on same branch). When no topic is active, changeset with topic will
be ignored and only bare one on the same branch will be taken in account.
There is currently two commands to be used with that extension: 'topics' and
'stack'.
The 'hg topics' command is used to set the current topic, change and list
existing one. 'hg topics --verbose' will list various information related to
each topic.
The 'stack' will show you information about the stack of commit belonging to
your current topic.
Topic is offering you aliases reference to changeset in your current topic
stack as 's#'. For example, 's1' refers to the root of your stack, 's2' to the
second commits, etc. The 'hg stack' command show these number. 's0' can be
used to refer to the parent of the topic root. Updating using 'hg up s0' will
keep the topic active.
Push behavior will change a bit with topic. When pushing to a publishing
repository the changesets will turn public and the topic data on them will
fade away. The logic regarding pushing new heads will behave has before,
ignore any topic related data. When pushing to a non-publishing repository
(supporting topic), the head checking will be done taking topic data into
account. Push will complain about multiple heads on a branch if you push
multiple heads with no topic information on them (or multiple public heads).
But pushing a new topic will not requires any specific flag. However, pushing
multiple heads on a topic will be met with the usual warning.
The 'evolve' extension takes 'topic' into account. 'hg evolve --all' will
evolve all changesets in the active topic. In addition, by default. 'hg next'
and 'hg prev' will stick to the current topic.
Be aware that this extension is still an experiment, commands and other
features are likely to be change/adjusted/dropped over time as we refine the
concept.
topic-mode
==========
The topic extension can be configured to ensure the user do not forget to add
a topic when committing a new topic:
[experimental]
# behavior when commit is made without an active topic
topic-mode = ignore # do nothing special (default)
topic-mode = warning # print a warning
topic-mode = enforce # abort the commit (except for merge)
topic-mode = enforce-all # abort the commit (even for merge)
topic-mode = random # use a randomized generated topic (except for merge)
topic-mode = random-all # use a randomized generated topic (even for merge)
Single head enforcing
=====================
The extensions come with an option to enforce that there is only one heads for
each name in the repository at any time.
[experimental]
enforce-single-head = yes
Publishing behavior
===================
Topic vanish when changeset move to the public phases. Moving to the public
phase usually happens on push, but it is possible to update that behavior. The
server needs to have specific config for this.
* everything pushed become public (the default):
[phase]
publish = yes
* nothing push turned public:
[phase]
publish = no
* topic branches are not published, changeset without topic are:
[phase]
publish = no
[experimental]
topic.publish-bare-branch = yes
In addition, the topic extension adds a "--publish" flag on 'hg push'. When
used, the pushed revisions are published if the push succeeds. It also applies
to common revisions selected by the push.
One can prevent any publishing to happens in a repository using:
[experimental]
topic.allow-publish = no
list of commands:
stack list all changesets in a topic and other information
topics View current topic, set current topic, change topic for a set
of revisions, or see all topics.
(use 'hg help -v topic' to show built-in aliases and global options)
$ hg help topics
hg topics [TOPIC]
View current topic, set current topic, change topic for a set of revisions, or
see all topics.
Clear topic on existing topiced revisions:
hg topics --rev <related revset> --clear
Change topic on some revisions:
hg topics <newtopicname> --rev <related revset>
Clear current topic:
hg topics --clear
Set current topic:
hg topics <topicname>
List of topics:
hg topics
List of topics sorted according to their last touched time displaying last
touched time and the user who last touched the topic:
hg topics --age
The active topic (if any) will be prepended with a "*".
The '--current' flag helps to take active topic into account. For example,
if you want to set the topic on all the draft changesets to the active
topic, you can do: 'hg topics -r "draft()" --current'
The --verbose version of this command display various information on the
state of each topic.
options ([+] can be repeated):
--clear clear active topic if any
-r --rev REV [+] revset of existing revisions
-l --list show the stack of changeset in the topic
--age show when you last touched the topics
--current display the current topic only
-T --template TEMPLATE display with template
(some details hidden, use --verbose to show complete help)
