Comment #35 on issue 2801 by address@hidden: Patch: Approximates  
cross-staff slurs in VerticalAxisGroup vertical-skylines.

Before reverting it, what I'd like to see is some sort of call-by-call map  
of the related code seeing what values are being sent in as inputs and what  
is being returned as outputs.  I agree that this is problematic and should  
be squashed, but it makes it easier to work on if it is already in master.   
Also, it could be the case that there is actually interaction between 2815  
and this patch, in which case that's important to know.  I would only  
revert it if somehow the code makes other parts of LilyPond regress or if  
the cause seemed so esoteric (some unknown phenomenon related to g++, for  
example) that it was too much of a question mark to have in current master.
