Note extension lines

[Andrew Bernard]

Greetings All,

How would one achieve the effect seen in the attached image, special notehead duration extension lines? I’m not quite sure where to start, how to attack the problem. I had a look at the flat glissando code on the list from 2012, but the difference is I need to be able to specify an arbitrary length, and unconnected to a following note. Just a pointer in the right direction would be good - I think I can write the code.
