        Summary: Warnings from simultaneous slurs with parallel music

Comment #1 on issue 1884 by address@hidden: Warnings from  
simultaneous slurs with parallel music
http://code.google.com/p/lilypond/issues/detail?id=1884

Actually, this has nothing to do with partcombine. Rather, before 2.14  
there were  no errors at all for double slurs, they were silently discarded  
without any warning (and some slurs might have been missing from the user's  
output without any indication).

Here's a minimal example:

%%%%%%%%%%%%%%%%%%%%
\version "2.15.11"
\relative c'' {
  c4
  << { c4( d) } { a4( b) } >>
}
%%%%%%%%%%%%%%%%%%%%

The problem is that there are really two slurs starting in the same voice  
at the second quarter (one from the c4 and one from the a4).
