Attached is a bit of LilyPond which has a slur over a line break. At the

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?
Yes, look for \alterBroken in the docs.
Is this a known bug?
Yes, or at least partly so:

comment in there, in case you have something to add.
Well, it looks like you have it covered there. FWIW I further whittled
my example down and found that varying the global-staff-size I could
vary the response markedly. Which is what the bug report is alluding to
when it says "in tight spacing situations" I guess.
