Thorsten,
    I looked that up and played with it.  After having played with it for a
while, it seems that povray only uses the length of these vectors in order
to scale the field of view.  It on the other hand, does not seem to care in
which direction they are facing.

For instance, even when the vectors are on regular axeses like:
camera {
      location <87.45355,-5.39098,49.71675>
      up y
      right x
      look_at <51.52028,-5.39098,13.78348>
}

it looks exactly the same as:

camera {
      location <87.45355,-5.39098,49.71675>
      up x
      right y
      look_at <51.52028,-5.39098,13.78348>
}

Is this because look_at only cares about the lengths of up and right?
