two questions

[Michiel Lange]

Hello everybody,

I hope this question is not very hard, but I have it with a few songs now:

when I create a part like this

foo = \notes
{
   c4 d e f g a b c r4
}

bar = \notes
{
   e4 b c d a g
}

and then reuse those parts like this

\relative c''
{
   \foo
   \bar
   \foo
   \bar
   \foo
   \bar
}

The music shifts up one octave (quite logically)
I "fixed" it so far with \octave c'' wherever it would go wrong...

Is there a way to prevent this (as \octave c'' will give warnings, and 
is not the best solution) ? I was thinking about an invisible, unheard 
note that would prevent octave shifting... or is there a better way?

A second question is about repeats and alternative endings
In the examples in the documentation  is an example that would do the 
first alternative three times, and the second the fourth (page 62 in the 
manual for version 2.2.0)
I was wondering if it could easily be done the other way around: the 
first alternative once, and the others the rest of the time 
automatically... I'm fairly certain that this is very doable with manual 
repeat commands (page 62 - 63)

OS: Slackware Linux,
Lilypond 2.2.0

Thanks in advance
Michiel
