last line, left justify?

[Jeremy Cowgar]

I typeset a piece that was just a tad too cramped and Lilypond did not break a
line, so I added a \break at an appropriate place, but it leaves only a few
measures for the last line and it really, really stretches it out to make it
fill the whole line.

Can I make Lilypond just make the last line of this piece left justified
instead of making it extend the whole width?

Thanks,

Jeremy
