Problem with \triangle ##f

[Aaron Dalton]

I'm using v.2.10.19 on FreeBSD and am trying to use the \markup{\triangle 
##f} command.  When I do, however, I get the following error.

Renaming input to: `21.ly'
/home/aaron/lilypond/usr/bin/../share/lilypond/current/ly/init.ly:45:70: 
error: syntax error, unexpected $end
   (apply ly:make-book $defaultpaper $defaultheader toplevel-scores)))

This happens even if I run lilypond itself instead of lilypond-book.  The 
odd thing is that \triangle ##t works just fine.  I just don't want it 
filled in :)

Thanks for your time.
