New issue 1971 by address@hidden: Slashed flags no longer work
http://code.google.com/p/lilypond/issues/detail?id=1971

The NR  
(http://lilypond.org/doc/v2.15/Documentation/notation/special-rhythmic-concerns)says:

"The slash through the stem found in acciaccaturas can be applied in other  
situations

\relative c'' {
  \override Stem #'stroke-style = #"grace"
  c8( d2) e8( f4)
}"

However, between 2.15.7 and 15.9 the slash has disappeared.  Labelling this  
as critical, even if it might have been intended, since if there is an  
alternative we should document it in the appropriate place.
