fix(docs): improve adjacent list items

Problem:
List items separated by blank lines are wrapped in "blocks", then the
html generator does not treat them as contiguous list-items, and the
browser shows the list as "1. 1. 1." instead of "1. 2. 3.".

Solution:
- When generating a list-item, check if the last child of the previous
  block was a list-item, and merge them together.
- Massage the help source.
