You might like to weigh up the benefits or drawbacks of using standalone
Denemo Directives instead. There is a convenience function for these as
well, something like:

(StandAloneDirectiveProto (cons "LigatureStart" "\\["))


Here is a complete example:

;;;LigatureEnd
(let ((tag "LigatureEnd"))
        (StandAloneDirectiveProto (cons tag "\\]  ") #f)
        (d-DirectivePut-standalone-graphic tag "\n]\nDenemo\n40")
        (d-DirectivePut-standalone-gy tag 10)
        (d-RefreshDisplay)
        (d-SetSaved #f))

I've used the graphic field to display a large (40pt) "]" character and
positioned it +10 in the y direction so that it sits on the staff
nicely.

I could put a pair of these in the Directives->Typesetter->Spanning
directory if you would like. Can you supply the "Help" text?
