Slurs at line breaks

[Jonas Müthing]

Hello lily-users,

I have the following problem: I need to layout some music for a  
scientific publication and the author of the article wants a few  
general changes on the layout. Right now there is own main problem I  
seem not to be able to solve:

When a slur goes over more than one line, the lilypond prints the slur  
into the last bar line and starts the slur on the next line very close  
to the key signature. I would like to change this an achieve a result  
similair to the tie-behaviour. Is there any way to do so?

Thanks a lot for your help.

Jonas
