Your other patch reminded me that I still had this on my ToDo list. 
Committed now, but I've made some additional changes after that.

I've not included the URL to partman-auto-recipe.txt in the example, for 
two reasons:
- it would not work correctly with the conversion of the file to text
- even if I made that work, the resulting line would become too long for
  my liking

Instead I've added the URL link in a paragraph before the example, so it 
will at least be available in the HTML and PDF versions.

Cheers,
FJP

P.S. I noticed that RAID preseeding is already documented. That now also 
has a reference to the README (which I moved to the same location as 
partman-auto-recipe.txt).
