Thanks for the info.

Indeed.
Though, I'm not aware we have a built-in-functionality to do this in
an automated way.
We_ have_ the completition_Head_engraver (or however it was
spelled...), but it's of kind all or nothing.

Nevertheless, I think I'll disregard something like

\score {
  \relative c'' { \tuplet 3/2 { c2 b \bar "" \break a } }
  \layout { line-width = 50 }
}

as a far too extreme border-case.


But here something really annoying, look at the out put of

\relative c''' {
  \voiceOne
  \repeat unfold 12 \times 2/3 { a'4 b, c \noBreak }
  \break
  \voiceTwo
  \repeat unfold 12 \times 2/3 { a,,,4 b' c, \noBreak }
}

You'll see the bracket already _wraps_ around the stems in the upper
staff, but not in the lower one. Furthermore this changes for the
upper staff, if not so tight spacing is forced or for lower pitches.
And again in the staff below the TupletBrackets doesn't change their
behaviour while doing loose spacing or higher pitches.

My codings for a tuplet-curve instead of a bracket rely on the
default-bracket. Up to now the behaviour of the brackets is hard to
predict with a reasonable coding, I guess a bug is in the game.
