New issue 1931 by brownian.box: Doc: MMRs 'staff-position = #0 should be  
revised
http://code.google.com/p/lilypond/issues/detail?id=1931

Since #'staff-position = #0 does not place MMR to "default position",  
Notation Reference sould be corrected:

http://lilypond.org/doc/v2.15/Documentation/notation/writing-rests#full-measure-rests , "Positioning  
multi-measure  
rests".

Please, how _critical_ it is?
