  $ hg up other

  switching to topic other

  0 files updated, 0 files merged, 4 files removed, 0 files unresolved

  $ hg topic --list

  ### topic: other

  ### branch: default

  t2@ c_b (current)

  t1: c_a

  $ hg phase --public 'topic("other")'

After changing the phase of all the changesets in "other" to public, the topic should still be active, but is empty. We should be better at informating the user about it and displaying good data in this case.

  $ hg topic

     foo

   * other

  $ hg stack

  ### topic: other

  ### branch: 

  $ 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
