[Orgmode] [patch] Terminating lists by indentation of #+SPECIALS too

Hello Carsten,

there was much discussion about a terminator and I ran into a problem,
that made me think we need one. But then I found we had one --- it's
just not used on HTML export.

Below is a little file I wrote. Thanks to the `- __' items, it results
in the XHTML closely to what I wanted it to.
But only as long as I use those _undocumented_ `- __' items. Once you
remove them, you'll see, that the `#+html: </div...' stuff ends up
inside the last list item and the XHTML will not validate.

As I looked at it, I found the most natural solution would be, to
terminate the list by regarding the indentation of `#+WHATEVER' and
`#+BEGIN_WHATEVER' if inside lists [fn:1].

The patch below (diffed against `remove-compatibility-code') makes
XHTML-export honor the indentation of `#+SPECIALS'.

Here's the Org-file I wrote (remove and add the `- __' list items to see
the effect):

#+OPTIONS: toc:nil
#+STYLE: <style type="text/css">
#+STYLE: body,p,div,td{font-size:13px;font-family:sans-serif;}
#+STYLE: div { text-align:left; }
#+STYLE: #content {width:550px;
#+STYLE:     margin-left:auto;margin-right:auto;text-align:center; }
#+STYLE: #postamble { width:550px;clear:both;border-top:1px solid black;
#+STYLE:      margin-left:auto;margin-right:auto;text-align:center; }
#+STYLE: </style>

And, finally, the patch. I would have used the function
`org-export-html-close-lists-maybe' but that didn't work, so I wrote
similar code just in place.

Carsten: If it makes things easier for you, I could apply the change to
the master branch and send an appropriate patch.

[fn:1] `org-end-of-item' and `org-end-of-item-list' already consider the
       decreased indentation of the `#+html:' line the end of the list.

       You can proof that by deleting the last dot and all empty lines,
       so that the `#+html:' line is directly below the last list
       item. Then move point somewhere on the item and do `M-x
       org-end-of-item RET'.
