Documentation enhancements

[Ruud van Silfhout]

Hi Graham,

I just have read the new manual for 2.3. It looks really great!
I have a few remarks.
1. In te section 'Orchestral music', subsection 'System start delimiters',
the second example.It states there that the group is a StaffGroup, but the
example code shows a GrandStaff.
2. To add lyrics to music two methods are supplied; the 'addlyrics' and
'lyricsto'. I could find the difference between those two methods; so it is
not clear to me when to use the one and when the other.
3. Questions I have seen more than once on the lilypond user group
concerning the multimeasure rests.  Two styles of MM-rests are supported.
Normally this switches after 10 rests. How can this be switched at some
other some 'user'-definable number of rests.
4. I once mailed a template for a SATB-choir-staff with piano accompaniment.
Is that something to add to the templates part of the manual?
5. The picture in the 'Creating titles' sub-section runs over the text below
it (or at least in the PDF version of the document I have printed)
Keep up the good work!

Regards,
