Yes, there are, reason for such patch.

In some style I'm working on for the site I'm publishing, I'm using a quite
large banner in black background as site's preamble. That works OK.

But, even for exporting a single page (no publish, I mean, just `C-x C-e b'),
I got this black background coming into play, while I had *no preamble set* for
those orphan pages.

Hence, the patch to remove such a preamble when it is essentially empty.

Best regards,
  Seb
