span arpeggio and single notes

[Robin Bannister]

> 
      
When the connectArpeggios mode includes an arpeggio on a single note, 
the resultant span arpeggio may collide with a previous note.        
      
      
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.12.1"
      
ddddd = { d'16 d'16 d'16 d'16 d'4 \arpeggio } % single note
sdf = { s4 <d' f'>4 \arpeggio } % chord
      
\score {
  << \transpose c c'{ \ddddd \sdf } \\ { \sdf \ddddd } >>
  \layout {
    line-width = #66 
    \context {
      \Staff 
      \consists "Span_arpeggio_engraver"
      connectArpeggios = ##t
    }
  }
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
      
      
In span-arpeggio-engraver.cc it says:              
>  we can't kill the children, since we don't want 
>  the previous note to bump into the span arpeggio
      
When arpeggio.cc prints a squiggly arpeggio on a single note, it warns  
>  no heads for arpeggio found?  
and kills the arpeggio.  
      
      
There is another demo and a proposed workaround on the user list at
