New issue 1411 by RalphBugList: Piano phrasing slur collision with lyrics
http://code.google.com/p/lilypond/issues/detail?id=1411

\version "2.12.3"

%{
Phrasing slur becomes highly eccentric within a single voice when it must  
move
across piano staves, and does not detect collision with lyrics on an  
adjacent
staff.

Specifically related to when the slur is forced to the up direction, either  
by
voicing (as per this example) or by a macro like \phrasingSlurUp
