manual needs help with ancient notation

[Graham Percival]

Hi guys, the examples in Documentation/user/notation.itely in the 
"Ancient notation" section need a lot of work.  Ancient notation is 
another weakness of mine; I have no idea what's changed between when 
these examples were written and current LilyPond.  Could somebody with 
a clue have a look at that section of the manual?

Most (all?) of them produce errors like this:
