Hi Rasmus,

Your patch to fix printing of h1 title when :with-title is nil looks good.

More comments below.

OK, I agree that the title being made blank not be tied with `:with-title`.

You can do this by setting title to an empty quote and Org will export it,
but you produce invalid HTML.  It’s actually a bug in ox-html IMO.

Here is my attempt to fix it (below is a whitespace ignored diff):

With above, a "blank" title will also result in a valid HTML, correct?
