Scheme get-option example in the docs...

[Reinhold Kainhofer]

The scheme example for ly:get-option in section 7.1.6 in the documentation 
(http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Functions-without-arguments)
has a small typo. In particular, it says 

   (if (eq? #t (ly:get-option display-bar-numbers))

while in fact it should be

   (if (eq? #t (ly:get-option 'display-bar-numbers))

(Notice the ' in front of display-bar-numbers!)

After that change, the example works.

However, on the command line I get the spurious warning

warning: no such internal option: display-bar-numbers

This is of course correct, since display-bar-numbers is not an internal 
option, but one defined/used by the .ly file itself. The warning also stays 
if I use ly:add-option to declare that option. Is this intentional? If so, I 
would change the warning to:

warning: No such internal option: display-bar-numbers. However, your lilypond 
might define and use it.


Cheers,
Reinhold
