The lilypond-book directory tests features of lilypond-book, but it
doesn't any real comparison. Meaningful comparison would be to compare
PDF files (after processing with LaTeX) across versions, but we don't
have support for that in the build system, and the code involved is
much simpler compared to lilypond itself, that there is little value
in doing these tests.
