I never use markdown myself. Between the two of us, you are de facto the
expert.

This is problematic. There is a rule in "ox-md" that contradicts what
you are suggesting. From org-md-separate-elements's docstring:

  2. In an item, remove any blank line before the very first
     paragraph and the next sub-list.

As a consequence, we try hard to produce

  -   Foo 2:
      -   Foo 21
      -   Foo 22

instead of

  -   Foo 2:

      -   Foo 21
      -   Foo 22

which was the case in early versions of Markdown exporter. I guess we
should produce the latter only when the sub-list is followed by another
block element, e.g., "End of Foo 2 item".

WDYT?

I'm trying to generalize the rule. Your previous suggestion applied to
paragraphs. I wondered if it was the same with other block types, e.g.,
example blocks.
