If [getting durations from DevNull] not possible, then the
manual should be updated to recommend
explicit durations instead;
I don't know the answer to the first question, but let's assume
that it's no and update the manual accordingly. Could you
write up the necessary changes?
Wilco. And
In 2.11.14, if one enters a tuplet shorter than tupletSpannerDuration,
the bracket won't be terminated correctly. The bug didn't occur in
2.10.0.
A minimal example:
\version 2.11.0
\paper {ragged-right = ##t}
\relative c' {
\set tupletSpannerDuration = #(ly:make-moment 1 8)
