I was experimenting with this approach, but 'padding doesn't seem to respond
when set to a procedure. In the following snippet, the first override
works, the second doesn't. Am I missing something?
\version "2.14.2"
{
\once \override Script #'Y-offset = #(lambda (grob) -3)
c''1_-
\once \override Script #'padding = #(lambda (grob) 3)
c''1_-
}
