more refman.itely stuff

[David Bobroff]

I'm working on proof-reading the manual. From refman.itely starting on
line 1721:

This example shows two examples of the same music giving different
accidentals depending on the order in which the notes occur in the
input file:

@lilypond[raggedright,fragment,verbatim]
\set Staff.autoAccidentals = #'( Staff (any-octave . 0) )
cis'4 <c'' c'> r2 | cis'4 <c' c''> r2
| <cis' c''> r | <c'' cis'> r | 
@end lilypond

I'm not entirely clear what this example is supposed to illustrate.  Am
I missing something, or does the example need to be altered?
