I've been trying to typeset a file using these wavy lines with LilyPond
22.2 and it throws an obscure error (this is after running convert.ly).

/usr/share/lilypond/2.22.0/scm/output-ps.scm:272:49: In procedure
symbol->string in expression (symbol->string join):
/usr/share/lilypond/2.22.0/scm/output-ps.scm:272:49: Wrong type
argument in position 1 (expecting symbol): (quote round)
Exited with return code 1.

Attached is the vibrato.ily from before with an test example at the
end. I notice that a variable name "round" is used whose name clashes
with a Scheme procedure, but that doesn't seem to be the cause of the
problem. Any ideas?
