New issue 1545 by address@hidden: Volta repeat marks are  
misplaced in some circumstances
http://code.google.com/p/lilypond/issues/detail?id=1545

When a volta repeat begins on a staff which subsequently disappears  
(because there is no music), and there is a tempo marking before the volta  
marking, the tempo marking pushes the special ending mark to the right.  My  
example below (not terribly tiny, but needed to show the various  
situations) shows this happening on the first pair of lines, shows the  
effect of no tempo marking being present, and then shows where the staff  
does not disappear.  This effect was not present in 2.13.31 but appeared  
before 2.13.34.  The images below are of 2.13.51 (bad) and 2.12.3 (good).
