Errors while compiling \markup \auto-footnote example from NR Appendix A9.6

[James]

Mike,

The NR gives an example of using the \auto-footnote mark up of

--snip--

\markup {
  \auto-footnote a b
  \override #'(padding . 0.2)
  \auto-footnote c d
}

--snip--

However, regardless if I use 2.15.x* this example works until I remove the second \auto-footnote line

i.e.

\markup {
 \auto-footnote a b
 \override #'(padding . 0.2)
 % \auto-footnote c d
}

I get a compilation message:

GNU LilyPond 2.15.20
Processing `test.ly'
Parsing...
test.ly:9:2: error: syntax error, unexpected '}'
 
 }
fatal error: failed files: "test.ly"

This seems to be triggered by the \override above it - which isn't explained in the doc in context of this example - and if I remove that instead I get no compilation error and the \override seems to make no spacial difference I can see.

So is this specific example bad/poor/broken or is something else going on with \auto-footnote command?

* I believe this syntax is not available in 2.14.1 as I get an "unknown escaped string `\auto-footnote'" message as well as the "unexpected }" - which is the only stable I have installed at the moment.
