force tuplet bracket to beam side

[Jeffrey Trevino]

Hi there,

I've got a rogue tuplet bracket trying to span notes on the note side instead of the beam side, and I'd like to specify that the tuplet bracket should always be on the beam side. Internals tell me that I need to set ly:tuplet-bracket::calc-direction equal to -1, but I'm not sure what the syntax for that would look like. 

Here's code to reproduce the situation:

\relative c'' {
staff.override.tuplet_bracket = ly:tuplet-bracket::calc-direction = -1
\stemDown
  \times 4/5{c8[( \f a' \times 2/3{c8 \grace {a32 [ c b \p ]} a8 \afterGrace c {a32 [ c b ]}}} 
  \stopStaff \startStaff
  \override Staff.StaffSymbol #'line-positions = #'( 18 16 14 12 10  4 2 0 -2 -4 )
  \override Stem  #'no-stem-extend = ##t
  \times 4/5{a' c a cis
  \stopStaff \startStaff
  \override Staff.StaffSymbol #'line-positions = #'( 4 2 0 -2 -4 )
  \override Stem  #'no-stem-extend = ##f
  a,,} c
  \stopStaff \startStaff
  \override Staff.StaffSymbol #'line-positions = #'( -10 -12 -14 -16 -18 )
  \override Stem  #'no-stem-extend = ##f
\time 3/8
   a,, c a c])
}
