prune: add a test to demonstrate a bug

Test shows that pruning without any successor warns about creating
divergence which is not possible and is a false warning.

For the knowledge, this pattern of pruning (without any successor) an
already pruned cset is sometime used to keep successors locally but
vanish them at server side.

test of the rebase command
--------------------------

  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > interactive = true
  > [extensions]
  > rebase=
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
  $ echo "topic=$(echo $(dirname $TESTDIR))/hgext3rd/topic/" >> $HGRCPATH
  $ mkcommit() {
  >    echo "$1" > "$1"
  >    hg add "$1"
  >    hg ci -m "add $1" $2 $3
  > }
  $ logtopic() {
  >    hg log -G -T "{rev}:{node}\ntopics: {topic}" 
  > }

Check that rebase keep the topic in the simple case (1 changeset, no merge conflict)

Create a common base
  $ hg topic --clear

  $ hg commit -A -m "default2" file
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')

Update the common file in a topic
  $ hg topic myotherfeature
  marked working directory as topic: myotherfeature
  $ echo "B" >> file
  $ hg commit -m "myotherfeature1"
  active topic 'myotherfeature' grew its first changeset
  (see 'hg help topics' for more information)

Update the common file in default
  $ hg update --rev default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "A2" > file
  $ hg commit -m "default3"

Rebase the topic
  $ hg update --rev 5
  switching to topic myotherfeature

  $ hg rebase

inmemory rebase currently drops the topic.

BUG: inmemory rebase currently drops the topic.  This is the correct output
because of there's a config override.
