Thanks, but you can do that already.
Use --block-size="'1" and be sure you're using a locale
that uses the thousands-grouping byte you're used to:

    $ dd if=/dev/zero of=big bs=1k count=1 seek=1G
    ...
    $ LC_ALL=en_US ls -lgo --block-size="'1" big
    -rw-------. 1 1,099,511,628,800 2010-06-09 09:32 big
