\book {\score{\header{piece = "piece}}} bug

[Tuukka Verho]

This code:  
  
\book {  
 \score {  
   \header {piece = "piece"}  
      \new Staff {  
        c'4 c' c' c'  
      }  
   }  
}  
  
gives the following error: 
 
GNU LilyPond 2.7.38 
Processing `testi.ly' 
Parsing... 
testi.ly:3:16: error: syntax error, unexpected "\\header" 
 
                \header {piece = "piece"} 
testi.ly:4:16: error: syntax error, unexpected "\\new" 
 
                \new Staff { 
testi.ly: 0: warning: no \version statement found,  add 
 
\version "2.7.38" 
 
for future compatibility 
error: failed files: "testi.ly" 
 
 
 
It compiles without problems with lilypond 2.6. Unless the syntax has changed 
somehow (according to the documentation it doesn't seem to) this is bug which 
I think should be fixed before 2.8.
