Unexpected new line in numbered list

[lewtun]

The asciidoc conversion for numbered lists sometimes introduces a new line that causes the resulting HTML / PDF to be incorrectly formatted.

For example, the following markdown cell

1. one
1. two
1. three
1. four
1. five
1. six

produces the following asciidoc output

. one
. two
. three
. four
. five
.
six

The new line before six causes this item to be treated as part of the fifth one

Steps to reproduce

1. Download the sample notebook fastdoc_numbered_list.ipynb from this gist and place it in some folder, e.g. book
2. Run

   fastdoc_convert_all --path path/to/book --dest_path output

Environment details
