html errors in navigation bar for snippets

[Mark Polesky]

On this page:
http://lilypond.org/doc/v2.13/input/lsr/lilypond-snippets/index

scroll down to the Staff notation of the navigation bar, and
hover over some links. There are some errors here. For example,
all of the following links point to "Nesting-staves"

 * Non-traditional key signatures 
 * Printing metronome and rehearsal marks below the staff 
 * Quoting another voice with transposition 

Also, if you follow a link to the Staff Notation snippet page:
http://lilypond.org/doc/v2.13/input/lsr/lilypond-snippets/Staff-notation
Viewing the html source shows that some <a name="foo"></a> tags
appear more than once, which (I think) does not do anything. 
Shouldn't a name tag appear only once in a web page so it can
unambigiuously refer to one specific location on the page?

<aname="Nesting-staves"> appears 5 times.

Similar errors can be found elsewhere on the snippets list, but
maybe someone knows of way to quickly find them? I don't really
know how the html is generated, so I wouldn't know where to look.

Hope this helps!
