Comment #13 on issue 1567 by address@hidden: Add documentation for  
footnotes
http://code.google.com/p/lilypond/issues/detail?id=1567

I'm making headway into documenting the auto and (I prefer) manual
footnote commands.

However, I'm coming across something I don't understand why it doesn't work.

@lilypond[verbatim,quote,ragged-right,papersize=a8]
\book {
 \markup {
   \bold \italic { Poco a poco }
   \footnote
     \super 1
     \italic "1. Little by little"
 }
 \relative c' {
 a'4\f( b8)[ e] c4_ \markup { \italic { rit. }
   \footnote
     \sub 2
     \italic "2. Slow down"
   }
 dis?4
 \breathe
 }
}
@end lilypond

The first footnote works (I see the super 1 and the footnote itself)
but the second I only see the \sub 2. No footnote "2. Slow down" is
printed. I looked back at your explanation I pasted into
http://code.google.com/p/lilypond/issues/detail?id=1567

and cannot see what the difference is apart from this being attached
to note (as opposed to a grob).

What am I doing wrong?
