$ du -b m n
2       m
772     n
$ du m n
1       m
1       n
$ du -B 512 m n
2       m
2       n

I thought the info page said
Block size
The block size used for display is independent of any filesystem block

I wanted to see how many blocks it would use on a 512 block system.
Perhaps reword the info.  It seems I must move the files to a 512
block system before du will tell me.

By the way, -h should emit an error when used with things that make it
less human.  Or maybe still say something. Blocks perhaps.

$ du -hB 512 m n
2       m
2       n
