split: handle bookmarks instead of leaving them on precursor

Before this patch we were leaving the bookmarks on the precursor of the split
instead of moving them on the tip of the split chain. We add a test to verify
the behavior.

test of the split command

Basic case, split a head
  $ hg init testsplit
  $ cd testsplit
  $ mkcommit _a
  $ mkcommit _b
  $ mkcommit _c
  $ mkcommit _d
  $ echo "change to a" >> _a

To create commits with the number of split
  $ echo 0 > num
  $ cat > editor.sh << '__EOF__'
  > NUM=$(cat num)
  > NUM=`expr "$NUM" + 1`
  > echo "$NUM" > num
  > echo "split$NUM" > "$1"
  > __EOF__
  $ export HGEDITOR="\"sh\" \"editor.sh\""
  $ hg split << EOF
