Hi,

I assume you took my rewrite of Mark's code from
http://lilypond.1069038.n5.nabble.com/How-to-make-this-postscript-spanner-to-work-with-L-amp-R-bound-details-td204375.html#a204622

Ad 1.
The function 'wavyVibrato' is called with a list of numerical numbers.
Iiuc what you're after, try negative numbers.

Ad 2.
The original code does line-breaks as well as my rewrite.
I suspect you're additions to be the problem.
What exactly are these?

Cheers,
  Harm
