arpeggio example in Notation Reference - tiny edit

[Federico Bruni]

Hi,

I would have a very tiny edit for the documentation.

It's a very small detail and normal users of lilypond will laugh at 
me, but I think it's useful for newbies (like me).


Notation Reference, 1.3.3, section "Arpeggio":

This is the second example:

<c e g c>2\arpeggio
\arpeggioArrowUp
<c e g c>2\arpeggio
\arpeggioArrowDown
<c e g c>2\arpeggio
\arpeggioNormal
<c e g c>2\arpeggio

I think a newbie can't see immediately the four parts.
So I would write something like this:

<c e g c>2\arpeggio
\arpeggioArrowUp <c e g c>2\arpeggio
\arpeggioArrowDown <c e g c>2\arpeggio
\arpeggioNormal <c e g c>2\arpeggio

This way the structure is much more clear.

Regards,
Federico
