Paper's markdown export does not add new lines after headings

[rolfbjarne]

Repro:

* Create a document with headers of various sizes. Example: https://paper.dropbox.com/doc/Heading-1--AzyT0uirpi4QxYb_nyvxpj4PAg-ZQMtWF42y44Xu2rLhILLz

* Export to markdown

* The result is markdown which does not have newlines after the headers (the output violates the MD022 markdown lint rule: https://github.com/DavidAnson/markdownlint/blob/master/doc/Rules.md#md022---headings-should-be-surro...)

Example output (for the link above):

# Heading 1
some text after heading 1 (no newline before this line)

## Heading 2

some text after heading 2 (newline before this line, but not after)
**Heading 3**
some text after heading 3 (no newline before this line)

Hi @rolfbjarne, thanks for messaging the Community!

In your Paper document, it looks like you’re not using heading 1, since this is the title of the document, and not a heading within the doc itself.

Could you try using a separate line in the doc for heading 1 to see if you get the same behavior?

Heading 3 is also using the bold function, so isn’t technically heading 3. The ### is the same as ** for bold text in Paper currently, so there wouldn’t be a new line afterwards since heading 3 isn’t officially implemented.

Keep me posted!

Yes, you're right, adding a heading 1 after the title works.

That said, I think there should still be a newline after the title.

Gald to hear that it works on your docs, @rolfbjarne.

Regarding the newline, if you wish, you can suggest this change for others to vote on, so the dev team can look into this in future!
