Yes, of course. I wasn't aware of the implications either – putting
glissando lines between fingerings is quite straightforward, but I had
to use glissandoMap and some trickery to create a satisfactory result.

My current project includes a book with a violin and a guitar staff, and
an additional handout for guitar-only purposes with tablature added. My
focus was primarily on the first part, which has to be finished in terms
of the layout as soon as possible for the illustrator to start to draw
the pictures to be added later. Therefore I missed the glissando line
suddenly pointing to nowhere in the tablature part.

Interestingly, I didn't see the spurious line on screen, but in a 
printoutthat I am currently using for practicing the guitar part that 
will be
recorded in a couple of days. I don't know whether others have made
similar experiences, but on screen nearly everything seems to look
correct.

Well, IIRC you were the first who mentioned the recursion error (which I
should have found myself – silly me).  But I have to admit that Harm's
solution works with scheme functions I understood at first glance,
whereas the grob-transformer stuff was not that easy for me to cope
with.

Conclusion: the list is great, and the fact that there are multiple
solutions to a problem makes it easier to find the most suitable
workaround ;-)
