Who's smoking rope, me or du?  I've got a 344,607 byte file on a 1K
filesystem (sizeof daddr_t == 4).  Both du and "ls -s" are reporting 341
blocks, but I only count 340.  It takes 337 blocks for the data, so I
come up with:

						data	total
    10 data blocks				  10	  10
    1 single ind. block + 256 data blocks	 256     257
    1 double ind. + 1 single ind. + 71 data	  71      73
						-----	-----
						 337     340

Am I missing a 341st block somewhere?
