A few comments: it seems overkill to produce an actual music expression
here when the purpose is to correlate input position with remarks.
While it has the advantage of only writing out expressions put into
\writeRemark, there cannot be any location different from the current
input location anyway. And that's available as (*location*) in a scheme
function already and passing it through a music expression will just
lead to duplicates or omissions (depending on how often the music
expression is placed in a \writeRemark).
