topic: display a hint pointing at help when a topic becomes non-empty

This is an attempt at avoiding "mistakes" by new users of topics when
they pull a topic and publish its changesets while being checked out. In
this case, the topic will become empty but still be active; however, if
this is a "foreign" topic, the user will not likely want to keep it
active for the next commit operation. So we add a hint message pointing
at general help of "topics" command so that they can eventually do
something and learn about "hg topics --clear".

  $ cd jungle

Test NGTip feature
==================

Simple linear case

  $ echo babar >> jungle
  $ hg add jungle
  $ hg ci -t elephant -m babar
  active topic 'elephant' grew its first changeset
  (see 'hg help topics' for more information)

  $ hg log -G
  @  4 (elephant) babar
  |
  o  3 () c_delta
  |
  o  2 () c_gamma
  |
  o  1 () c_beta
  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta


multiple heads with topic

  $ hg up "desc('c_beta')"
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo zephir >> jungle
  $ hg add jungle
  $ hg ci -t monkey -m zephir
  active topic 'monkey' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg log -G
  @  5 (monkey) zephir
  |
  | o  4 (elephant) babar
  | |
  | o  3 () c_delta

  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta

one of the head is a valid tip

  $ hg up "desc('c_delta')"
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo epsilon >> epsilon
  $ hg add epsilon
  $ hg ci -m "c_epsilon"
  $ hg log -G
  @  6 () c_epsilon

By default histedit should edit with the current topic only
(even when based on other draft
