Since the issue is that fonts are not embedded, I wondered if the 
solution is as simple as embedding them after the fact.  The important 
missing fonts in question are shipped with LilyPond, so then it was 
matter of looking online for a little bit of GhostScript:

    gs -o path-to-fixed.pdf \
      -sDEVICE=pdfwrite -dEmbedAllFonts=true \
      -sFONTPATH="path-to-fonts" \
      path-to-broken.pdf

On my system, "path-to-fonts" would be:

    /usr/local/lilypond/usr/share/lilypond/current/fonts/otf/

Running the command against all of the 2.19.82 PDFs from the web site, 
the results are a significant improvement.  There were only a few 
substitutions due to additional missing fonts, but those are largely 
irrelevant (i.e. "LuxiMono" used as an example of overriding the 
typewriter font).

Something for folks to consider to tide us over until the next release.
