Sort of moot at this point, I did a largeish rewrite. (Attached, I  
should be able to rsync it up to the site tonight.)

There are currently three obvious problems with it, all to do with vfat:

1) it always prints a LABEL even if it's all spaces or the magic "NO  
LABEL" value.

2) The funky 32 bit uuid is printed big endian, when the other prints  
it little endian.

3) It prints the uuid hex all lower case, where vfat is uppercase and  
ext2 is lowercase. (Sigh.)

(And of course I haven't implemented the suid zero argument behavior  
yet.)
