Jean-Pierre, your memory is much better than mine. But now you've posed
another interesting puzzle: The archived copy of your hack has been
sanitized around most of the "@" characters :-( But I found your message in
my personal archive; here's the hack for anyone who's interested:
================================
\input musixtex
