Thanks for the heads-up, I didn't know about that.
Unfortunately, it will not work for us, for several
reasons: first, we are still using texi2html, not
makeinfo (and even the decade-old texi2html 1.82!),
and second, the highlighting is done by Pygments,
not by source-highlight. While source-highlight does
have some level of support for LilyPond, it is old,
a number of syntactic features are not supported, and
the lexer has not been updated for newer LilyPond
versions.

Best regards,
