New issue 1254 by tdanielsmusic: Pre-defined commands cannot be used in  
\context blocks
http://code.google.com/p/lilypond/issues/detail?id=1254

IWBN if predefined commands could be placed in \context blocks so their  
scope could be modified, but this code gives a syntax error, "unexpected  
MUSIC_IDENTIFIER":

\score {
  \relative c'' { a1 \f }
  \layout {
    \context {
      \Score
      \dynamicUp
    }
  }
}

Whereas substituting the exact expansion works fine:

\score {
  \relative c'' { a1 \f }
  \layout {
    \context {
      \Score
      \override DynamicText #'direction = #UP
      \override DynamicLineSpanner #'direction = #UP
    }
  }
}
