Problem with fingering

[Tomas Valusek]

Hello,

let's modify slightly a snippet from NR 1.7.1, section Fingering 
Instructions:

\relative c' {
  \set fingeringOrientations = #'(left)
  <c-1 d-2 a'-5>4
  \set fingeringOrientations = #'(down)
  <c-1 d-2 a'-5>4
  \set fingeringOrientations = #'(down right up)
  <c-1 d-2 a'-5>4
  \set fingeringOrientations = #'(up)
  <c-1 d-2 a'-5>4
}

What we get? See attachement.

AFAIK, numbers in chord fingering should be one directly above the 
other, not shifted sideways. Si this a bug?
