df reports size incorrectly when used with "-B"

[Nilmoni Deb]

Using df (coreutils) 4.5.7. 

/> /bin/df -T -m
Filesystem    Type   1M-blocks      Used Available Use% Mounted on
/dev/hda5     ext2        3444       696      2573  22% /


/> /bin/df -T -B M
Filesystem    Type   1M-blocks      Used Available Use% Mounted on
/dev/hda5     ext2       3444M      696M     2573M  22% /

The 1st command says there are 3444 1M-blocks blocks, which makes sense.

The 2nd one says there are 3444M 1M-blocks, which is superfluous at best
and erroneous at worst, since this partition does not have 3444 million
million bytes !!

In fact, this problem is there for all options when used with the "-B"
option.

As a suggestion, u could show it this way for "/bin/df -T -B M":

Filesystem    Type       Total      Used Available Use% Mounted on
/dev/hda5     ext2       3444M      696M     2573M  22% /

This would make it more consistent.
