error in manual?

[Julian Peterson]

I think I found an error in the lilypond documentation for 2.8.x, 
although as I'm still quite new to lilypond there is a good chance that 
it's my own misunderstanding...

Section 4.5 contains this snippet:

padText = #(define-music-function (parser location padding) (number?) #{ 
\once \override TextScript #'padding = #$padding #})

Which seems to contain an extra # preceding $padding.  I had to remove 
it to get this example to work, and further examples seem to be 
consistent with using only a $.

Thanks,
Julian Peterson
