Consecutive Markdown blocks sometimes get eaten up

[roncli]

If you have a series of Markdown blocks that look like this:

/*
# Heading 1
*/
/*
## Heading 2
*/
/*
### Heading 3
*/
###
GET /some/url

Sometimes, httpbook just straight up deletes headings 2 and 3.

The fix appears to be to add ### between Markdown blocks, but the fix is only temporary.
