Nested list on  Client side Editor broken

Neither of the following nested lists correctly on the Client Side Editor (live version at http://www.toptensoftware.com/markdowndeep/dingus as of 21/01/2016).

Six separate single-item lists are produced rather than two nested lists.

```
* L1
  1. L2
* L1

1. L1
  * L2
2. L1
```
