Didn't see your patch from a year ago when I first looked at pr#1273. I 
will try it this evening. Looks like it will block the bad file names 
that display with attribute 0xf. However, think it should also skip it 
if just the volume label bit is set (since I see volume labels display 
as files with ls too).
Thanks!
