line breaking newbie question

[Rupert]

Hi,

I'm just getting started with lilypond which, by the way, is looking
fantastic so far.

I'm having trouble with line breaks. I want raggedright output, by
which I mean I want to break no matter how short that will make the
current line if the current line would otherwise be too wide for the
page. I can't seem to get this... could someone please tell me what
I'm doing wrong in this short example?

Cheers,
Rupert
