I tried to add this to the LSR (along with the other example from Vincente) but 
your snippet failed to compile there. I assume therefore that this will only 
work with a 2.13.x version?

PS @LSR People, I have added both examples and this one has most of the 'meat' 
commented out with '[Needs LSR Update] in title which I think is the correct 
policy? Also the original example should probably have its title changed to 
'bracket' rather than 'parenthesis' only that these last two examples 
explicitly use the 'parenthesis grob/engraver' (?).
