2.7.9 tie-dot collission

[Henrik Frisk]

Many of the issues regarding ties brought up in the examples in a previous post
(http://lists.gnu.org/archive/html/lilypond-user/2005-09/msg00141.html)
are resolved in 2.7.9. However, there is still a collission between ties
and dots on notes on ledger lines with ties down (notes in spaces are
fine).
