-m was deprecated in 2001
http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commit;h=d1772031
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`
http://lists.gnu.org/archive/html/coreutils/2010-09/msg00028.html
Also there was a previous request for `df -g` and `du -g`
http://lists.gnu.org/archive/html/bug-coreutils/2009-12/msg00000.html
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.
cheers,
Pádraig.
