This patch seems to correct the issue, but I don't know if it's the
correct fix (or if there are any side effects I'm unaware of).

I get this output:

  GNU LilyPond 2.13.6
  Processing `bad.ly'
  Parsing...
  bad.ly:4:16: error: syntax error, unexpected MUSIC_IDENTIFIER
       Määä A♯ B♭ 
                  \break
  error: failed files: "bad.ly"


If the patch looks okay, I'll add a commit summary for completeness.

Thanks,
Patrick
