Hi Ole,
I think you're right that there's a (hard to detect) bug.
I'll review the expect behaviors here for the list.
(Valentin, the example here is too big for the tracker ... I'll cut down to
something minimal later today.)
The basic principle behind tupletFullLength[Note] (as I understand it):
Turn the context setting tupletFullLength on to ... well, give tuplet
brackets their full length. Vanilla tuplet brackets end just at the right
edge of the tuplet-final note; full-length tuplet brackets, on the other
hand, extend farther to the right. How much farther to the right do
full-length tuplet brackets extend than vanilla tuplet brackets?
The answer to this question is determined by a second, companion context
setting named tupletFullLengthNote.
Turn the context setting tupletFullLengthNote on to make full-length tuplet
brackets cover *all nonrhythmic notation right up until the following note*;
turn tupletFullLengthNote off to make full-length tuplet brackets cover
*only the whitespace until the next bit of notation ... be it a clef, time
signature, key signature, or another note*.
In other words:
tupletFullLength = ##t, tupletFullLengthNote = ##t ==> tuplet bracket
covers clefs and stuff
tupletFullLength = ##t, tupletFullLengthNote = ##f ==> tuplet bracket does
*not* cover clefs and stuff
So we can think of tupletFullLengthNote as a type of *greediness* modifier
on tupletFullLength.
(And note that tupletFullLengthNote only makes sense when tupletFullLength =
##t.)
So ...
Running a test, we get the visual results attached to this mail (better to
just look at the png).

}

%%% END %%%
The png shows tupletFullLengthNote = ##t (the default) on the top staff;
The png also shows tupletFullLengthNote = ##f (nondefault) on the bottom
staff.
The behavior is exactly as I would expect *just before clefs and time
signatures*.
But the behavior is ever-so-slightly erroneous *just before normal gaps
between notes*.
I've marked the normal gaps between notes with red asterisks. The asterisks
center over the problem gaps.
CONCLUSION: I think the answer to your question is that tupletFullLengthNote
should make *no difference* between "normal" notes (ie, notes that do not
have any intervening nonrhythmic material like clefs and time signatures);
in other words, imo at least, tupletFullLengthNote should only matter when
there is intervening nonrhythmic material. But, alas, we see that this is
not truly case.
I'll extract a minimal example later today and Valentin can judge if it
belongs in the tracker.
