Fw: Augmentation dot positioning (issue #3179)

[Werner LEMBERG]

The fix for issue #3179 seems to be incomplete – look at the last
chord in each line of the attached image; there is always one dot too
much at the bottom.

Cf. `regression/chord-dots.ly'; this is controlled by the
`chord-dots-limit' property.

However, you have found a bug I think, since it doesn't seem to work
correctly for your case, eliminating dots on the wrong side of the
chord.
