If anybody still wants to work on this, it's a voicing issue:  the example  
starts off in the main voice, creates several new voices for the polyphonic  
section, then returns to the main voice.  This is problematic for slurs,  
since the objects they encompass must be visible (i.e., acknowledgable in  
the same context) for collision avoidance to work properly.

There are two solutions:

1) Continue using polyphony shorthand, but name the main voice `1': this  
ensures that the implicit \voiceOne notes (which are currently invisible to  
the Phrasing_slur_engraver) are created in the same context as the earlier  
notes;

2) Use explicitly instantiated voices for the second, third and fourth  
voices.

(alternatively, rewrite the whole section after the Mikuli edition :)
