Export to Markdown needs blank line between bullet points and heading

[nigelcharman]

1. Create a map with 3 levels with a couple of nodes at the 2nd level
2. Download as outline > Markdown
3. Select Outline Type of 2 heading levels + bullet points

The exported markdown file contains:

# Shipping
## Domestic
* Order costs $100, shipping is free
## International
* Order costs $40, shipping is $8.00

which is interpreted as:

Shipping

Domestic

• Order costs $100, shipping is free

  International

• Order costs $40, shipping is $8.00

In order for it to be interpreted correctly, a blank line is needed between the bullet points and the next heading.
