Fingering on right doesn't avoid dot

[nick . payne]

With a dotted note, if the fingering indication is set to be on the right then it collides with the dot. This is probably related to the bug I reported back in November where an accidental collides with the fingering if it's on the left.

\relative c'' {
    \set fingeringOrientations = #'(left)
    <dis c-4>4.
    \set fingeringOrientations = #'(right)
    <dis c-4>4.
}
