This patch restrict the format of topic names to make sure they consist only of
alphanumeric, '_' and '-' characters.

  $ 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
  
  (some details hidden, use --verbose to show complete help)
  $ hg topics

Test topics interaction with evolution:

  $ hg topics --config experimental.evolution=
  $ hg topics --config experimental.evolution= --rev . bob
  abort: must have obsolete enabled to change topics

Create some changes:

  $ for x in alpha beta gamma delta ; do
  >   echo file $x >> $x
  >   hg addremove
  >   hg ci -m "Add file $x"
  > done
  adding alpha
  adding beta
  adding gamma
  adding delta

Still no topics

Trying some invalid topicnames

  $ hg topic '.'
  abort: the name '.' is reserved
  [255]
  $ hg topic null
  abort: the name 'null' is reserved

  $ hg topic tip

  $ hg topic 12345
  abort: cannot use an integer as a name
  [255]
  $ hg topic '   '
  abort: topic name cannot consist entirely of whitespaces
  [255]

  $ hg topic 'a12#45'
  abort: invalid topic name: 'a12#45'
  (topic names can only consist of alphanumeric, '-' and '_' characters)
  [255]

  $ hg topic 'foo bar'
  abort: invalid topic name: 'foo bar'
  (topic names can only consist of alphanumeric, '-' and '_' characters)
  [255]

this is trying to list topic names
  $ hg topic ''

  $ hg topic '*12 B23'
  abort: invalid topic name: '*12 B23'
  (topic names can only consist of alphanumeric, '-' and '_' characters)
