Think that might just be your font.  Try it in fixed-width.

No, fairly modern (40GB 7200rpm) drive.

Debian sarge (or was it etch?) maybe 6 months old in parts (kernel at 
least is that old) but I'm running mildly older stuff elsewhere and not 
seeing anything like this.

I also tried it with several syncs and saw no difference until after the 
remount.

Heh.  It seems like plaintext files maybe were not as affected.  The 
problem appeared when one of my subversion repositories started to 
bitrot.  Most of the others were working fine, but a few had trouble 
dumping (I guess some bits got twiddled in the older revs.)  I'll have 
to check my website for pictures of jesus tomorrow.
