Instrument Name Spacing

[Bryan Stanbridge]

Greetings,

I'm using 2.4.5-1 on FC3 (the CCRMA package).

I've noticed that the horizontal alignment of an entire line seems to be 
done completely independantly of the short instrument names.  It seems 
as though the musical line stretches from margin to margin and the 
instrument names get shoved into the left margin.  The very first line 
works as I would expect, but from that point forward it's no good.  It's 
visible in this tiny example but far more obvious in a full score of 
many pages.

\book {
 \score {
   \new Staff {
     \repeat unfold 20 {c'4 c' c' c' \break }
   }
 }
}

I searched the archives and couldn't find anything relating to this 
specific problem.  Can anyone else reproduce this, and/or would 
upgrading to 2.6.x help?  (I'm trying to wait until CCRMA gets a version 
online, but I'm not totally adverse to compiling it myself if I have to 
do so).

Cheers,
Bryan...
