Tuplet bracket over tremolo

[Jay Anderson]

\version "2.13.15"
\new Staff
{
  %\override TupletBracket #'transparent = ##t
  \times 2/3 {\repeat tremolo 3 c'8}
}

In previous versions the above worked as expected: a '3' over a dotted
quarter with a eighth tremolo beam. (I've use this in 2.12 without
problems.) With the latest 2.13.15 release the brackets are now
visible and colliding with the number. Was this an intentional change
in behavior or a regression?

Easy workaround: make the bracket transparent.

Thanks.
