Hm, I've did a rebuild from scratch and immediately emptied the two
book_html.py files, and *now* I got an error upon trying to create the
HTML files. So while I think it wasn't related to the scripts itself it
had to do with the state of my build directory.

I finally found out where the code in book_html.py actually leads to.
With some brute force I  took care of replacing the snippet and image
with a paragraph that I could then grep in the rendered docs. And it
ended up exclusively in the lilypond-book regtests.

So obviously the book_XXX.py files are really for lilypond-book and
don't have anything to do with the building of LilyPond docs.

Which brings us back to the original issue: Where is the code that
generates the blockquotes with the LilyPond code snippets and images?

Probably David's pointer to texi2html is plausible, but I must say
reading through lilypond-texi2html.init doesn't really help. The
references to <blockquote> that David found obviously don't point to
LilyPond examples but rather to @example. And the rest of that file is
definitely not related to LilyPond code examples.

So it is really strange, I'm completely at a loss to find out where to
start looking further ...
