‘new text-spanner’ development

[Simon Albrecht]

Hello,

as the other thread was becoming a monster, I start up a new one.
I’ve now got a version of text-span-spread.ly, as I call it, and it 
compiles now. However, a new problem appeared, which I assume has to do 
with variable scope and seems to be over my head: The first call to the 
\startTextSpan music function sets the texts for _all_ the subsequent 
calls. Even more suspiciously, the tweak to font-shape in line 725 
(ugh…) is also applied to all these instances.
I’m sorry to call for help so soon again, but I just don’t have enough 
experience and background to troubleshoot this with any degree of 
efficiency. Any hints are welcome! :-)

Yours, Simon
