John Hendy pointed out [1] that
list
- item1
- item2
Isn't the same as this:
list
- item1
- item2
when exported using the `md' backend (or its derivatives). But it needs to
be to generate a proper document (at least with engines like pandoc.)
The attached patch enables this by adding a blank line after a
`paragraph', but before a `plain-list' as long as the `paragraph' is not
itself inside a list.
In other words, with the patch, the `md' export renders both lists with a
blank line after the preceeding paragraph.
HTH,
Chuck

Subject: [PATCH] lisp/ox-md.el: Fix lists following paragraphs
* lisp/ox-md.el (org-md-separate-elements): Add a line after a
paragraph that preceeds a list, but is not itself contained in a
list.
Markdown needs a blank line following a paragraph to understand that
a list really is a list. However, nested lists do not need this and
adding the blank line would result in extra whitespace when
formatted for display.

Thanks for your patch. I applied a different one, though.
I find blank lines rules in Markdown very unclear.
