No.  One bezier would do me, but there isn't a scheme output function
for a bezier that
I could find.  I'm trying to make the markup so it doesn't require any
changes to the 
Lilypond distribution, at least for right now.

If I wanted to use a single bezier, it seems to me that I'd need to add
a bezier procedure to output-*.scm.  I don't think I'd need to make any
changes to lookup.cc, unless I wanted to access beziers from c++
routines.  Am I reading this correctly?

Thanks for the help.  I could see I needed to quote the bezier parameter
list, but I had some other syntax that was messing me up.
