Basic case, split a head

  $ hg init testsplit

  $ cd testsplit

  $ mkcommit _a

  $ mkcommit _b

  $ mkcommit _c --user other-test-user

  $ 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
