OK, I asked the user to re-test this (cc'd) and he tells me that both 
the backup and includeurl scripts independently cause a blank line at 
the start of the html and wikibook xml output. However, I have installed 
includeurl on a test system and am unable to replicate the problem.

I'm waiting to hear the result of removing the closing ?> from the 
backup script, but I'm at a loss as to how to proceed with includeurl, 
given that I can't reproduce the behaviour.

Any suggestions would be welcome.
