Thanks for your response, Urs. This looks very close to what I need. If I can 
modify the solution so that the glissando terminates on an ordinary note (as 
opposed to a grace note) then it will be perfect.

In the archives I have found a post[1] by Piaras linking to a pdf of various 
effects, including this one, but it does not include the code used to acheive 
these effects. I also found a post[2] of yours in which you demonstrate the 
syntax as

    \stemmedGlissando #'(15 . #f) c'4 

which looks great, and state that Piaras wrote this function when you asked for 
such a function on the list. However, I was unable to find the thread in which 
he provided you with this function. Do you still have the code?

Piaras, I have cc'd you in case you can help out. I'll be very grateful if 
either of you can provide the code for stemmedGlissando.

Thanks,

Mason
