I can say that in writing Make.text this was something that
I ran into immediately.  So I had to figure out the rules
for when to put a blank line in, and the code has to keep
track of state to figure out whether to insert a blank line
when translating a <li>, <h2>, <blockquote>, etc.  And, the
current version does not do a perfect job, I'm going to have
to make the algorithm a bit more complicated to do that.

I think your proposed change would simplify things for Make.text.
You probably shouldn't change things to make it easier for
mechanical converters, though :-).

On the other hand, the complexity of a mechanical converter
like Make.text is probably an indication of the complexity
of understanding the rules for a human.

Q: are you saying that

    * foo
    * bar
      * baz

will become

    * foo
    
    * bar
    
      * baz

under your proposal?  And if so, will there be an equivalent
to the current

    * foo
    
      * bar

(which differs from
 
   * foo
      * bar

by an additional <p>)?

(BTW I also ran into the issue you mentioned previously
about ']' in link contents.  Writing Make.text has definitely
been useful for finding these issues.)
