musicxml2ly: wavy-line bug

[pls]

Hey all,

musicxml2ly v2.15.29 always converts  <wavy-line> elements as trill spans, i e 
wavy lines are always typeset in combination with a trill mark even when no 
trill mark is wanted/requested:

wavy-line.xml
Description: application/xml

The correct MusicXML markup for a trill mark in combination with a wavy line 
leads to the following result:

trill-mark-wavy-line-bug.xml
Description: application/xml

Possible solution: 
* trill marks in combination with wavy lines should be converted to 
\startTrillSpan ... \stopTrillSpan
* wavy lines without trill marks should be converted to text spanners 
((\once)\override TextSpanner #'style = #'trill ... \startTextSpan ... 
\stopTextSpan)
