I haven't yet pulled this patchset to generate the HTML/PDF docs, but
just looking at the comments themselves it looks reasonable to me ...
and I say this as being perhaps one of the stricter folks under
security/ when it comes to 80 character line lengths :)  In my
opinion, the benefit of being able to render the docs nicely outweigh
the pain of scrolling horizontally in my editor.  Thanks for doing
this Richard.

Does anyone else have any thoughts on these changes?
