Comment #25 on issue 1472 by address@hidden: Collision between MMR and  
key signature
http://code.google.com/p/lilypond/issues/detail?id=1472

Comment 21 notes the one restoration of 2.12.3 behavior that I did not like.
LeftEdge takes space from the notes, but only when one is created for a  
clef/signature spacing, and only on the first staff in the system.

In the next patch set I'll include the equivalent of
  \override LeftEdge #'extra-spacing-height = #'(+inf.0 . -inf.0)

Please do look for other problems.
