evolve: Fix crush when reading docstring

Before this patch, hg evolve --divergent could crush when looking
for docstring of function of merge.update. We were checking the
docstring to work properly with older version of Mercurial. It
could crush if an extension would wrap merge.update without
keeping the docstring. This patch fixes the crush.

Check we can find the topic extensions

  $ [ -e $TOPICROOT/hgext3rd/topic/__init__.py ] || exit 80
  $ cat >> $HGRCPATH <<EOF

  $ mkcommit() {

  $ hg topic bar
  $ mkcommit ggg
  created new head
  $ mkcommit hhh
  created new head
  $ mkcommit iii
  created new head
  $ mkcommit jjj
  created new head

Tests next and prev behavior
============================

Basic move are restricted to the current topic

  $ hg up foo
  switching to topic foo
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg prev
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [14] add eee
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [15] add fff
  $ hg next
  no children on topic "foo"
  do you want --no-topic
  [1]
  $ hg next --no-topic
  switching to topic bar
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [16] add ggg
  $ hg prev
  no parent in topic "bar"
  (do you want --no-topic)
  $ hg prev --no-topic
  switching to topic foo
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
