-m was deprecated in 2001

It is not mentioned in the info page as far as I can see
It's not specified by POSIX
It's not used in solaris
It _is_ used in FreeBSD

So this is much the same argument as supporting `dd bs=1m`

Also there was a previous request for `df -g` and `du -g`

The only reason one would support these is for compat with FreeBSD,
and if we did, we wouldn't want to promote their use through documentation.
