I was aware of the function `org-export-html-close-list-maybe' but I
couldn't get that to work. Now got it to work by adding a new parameter
to that function, saying, that it's first argument is raw HTML (see new
patch below).


There was another problem about paragraphs.
In this file, "*List ONE*" was wrapped in "<p></p>", while "*List TWO*"
was not:

* Some Lists

  #+HTML: <div style="width:48%;float:left;">

  *List ONE*
    - Item one
    - Item two

  #+html: </div>
  #+html: <div style="width:48%;float:right;">

  *List TWO*
    - Item one
    - Item two

  #+HTML: </div>

The new patch fixes this, too. That is, what the new
`org-open-par-maybe' is for. It's a corner case and I should keep it
for testing.




I published all my org-notes (more than 100 files) to HTML and they
validate better then before. So the patch might be save to apply.
