I've tried fixing this (I find it one of the most annoying bugs in
LilyPond; #379 was my first bug report), but it's not as simple as it
first appears: slurs have to avoid breakable objects in the middle of
a system, whereas phrasing slurs are assumed to live outside slurs
(hence benefit from slur avoidance behaviour).

I've attached a picture which shows the difference between the two:
the slur avoids the time signature, whereas the phrasing slur goes
straight through.   Making slurs match phrasing slurs isn't an option
here; the slur encompassing code needs to distinguish between
prefatory matter and the same items placed elsewhere.

Regards,
Neil
