Duration documentation

[Richard Shann]

Hi,

I found it a bit difficult to understand the format of duration in 
lilypond - I think two of the examples
given (in 2.6.5 documentation) are misleading:

the explanation of \partial duration is this:

   Partial measures, for example in upbeats, are entered using the 
|\partial| command:
   \partial 4* 5/16 c'16 c4 f16 a'2. ~ a'8. a'16 | g'1

but I think what was meant was 4* 17/16 for the duration, the example as 
given has the second
note straddling the first bar line. In addition the explanation for 
duration is this:

   You can alter the length of duration by a fraction N/M appending 
`|*|N/M' (or `|*|N' if M=1). This won't affect the appearance of the 
notes or rests produced.
   a'2*2 b'4*2 a'8*4 a'4*3/2 gis'4*3/2 a'4*3/2 a'4

I think the example was meant to be

a'2*2 b'4*2 a'8*4 a'4*4/3 gis'4*4/3 a'4*4/3 a'4

otherwise the final a'4 does not actually start at the beginning of the 
bar (as you can see by putting the bar in manually at this point and 
getting a barcheck failure).
