fingeringOrientations and StringNumber.direction broken?

[Malte Meyn]

Hi list,

I think I found one or two bugs or at least a *very* confusing 
inconsistency:

\overriding StringNumber.direction and \setting fingeringOrientations 
seem to have no effect but

\overriding Fingering.direction and \setting stringNumberOrientations 
have an effect.

IMO the output should be the same for the second, third, and fourth note.

\version "2.19.46"

{
  % Everything ok:
  g'\1-2

  % This looks broken to me:
  \once \override StringNumber.direction = #DOWN
  \once \override Fingering.direction = #DOWN
  g'\1-2

  \once \set stringNumberOrientations = #'(DOWN)
  % This looks broken to me:
  \once \set fingeringOrientations = #'(DOWN)
  g'\1-2

  % Everything ok:
  g'_\1_2
}
