RE: A slur across a line break with change of clef in another staff generates bad output

Richard,

Tried putting the "\clef treble" before the a8. Looks good to me, yet I do not 
know what other constraints you have.

Subject: A slur across a line break with change of clef in another staff 
generates bad output

Attached is a bit of LilyPond which has a slur over a line break. At the same 
moment the clef is changing in the lower staff. The result is a horribly broken 
slur start in the top staff.
I blindly applied the dragging-the-shape on this curve which generated the 
commented out offsets. This results in something half-way acceptable. The bug 
is sensitive to all sorts of things I think - this was the most I managed to 
pare it down - reducing the font size made it go away for example.

Questions:
        Is there special syntax for altering the shapes of the half-slurs at 
the end and beginning of the line?
        Is this a known bug?
