[bug] slur collisions / near-collisions

[Graham Percival]

Lilypond / fink 2.3.11

In this example, the first slur collides with the \pp.  It doesn't 
collide if I
only have that bar on its own, but when there's a full line of music, 
the slur
_does_ collide with the \pp.

In addition, the "fis--( fis-- fis--)" slurs seem very close to the 
"--"s.  This
isn't necessarily a bug; I just thought I should point out this case 
for examination.
