multiline header

[Alexandre Leray]

Hi,

first of all thanks for such a great syntax, so far it's the best I know!

I have a document with quite long titles and I was wondering if it was 
possible to hard-break them:

e.g.:

This is a veeeeeeeeeeeeeeeeeeerrrrrrrrrrrrry long title
=======================================================

would be

This is a veeeeeeeeeeeeeeeeeeerrrrrrrrrrrrry
============================================
long title
==========

Right now it produces two <h1/> tags.


Best,

Alexandre
