FAT12 format does not honor the -R option

["Michael T. Kloos" <michael@xxxxxxxxxxxxxxxx>]

"mkfs.vfat -F 12 -R 2 /dev/loop0" does not seem to honor the -R option.  
It just defaults to 0x20 for the reserved sector count. I can hexedit 
the FS to move the file allocation table contents and change 0x20 to 
0x02 in the reserved sector count field. Mounting this seems to work 
fine under the Linux FAT driver from my limited experimentation.  It 
just seems like a waste of space reserving that many sectors in a FAT12 
FS where it is most likely to be used in space constrained 
applications.  Is this a bug or is it working around some compatibility 
issue with 2 reserved pages?
