These are not standard options. While the coreutils version of df common on Linux has an undocumented -m option it does not have -g. Solaris' df does have -g, but it has a different use: "Prints the entire statvfs(2) structure". I wouldn't object to -m as those OS which have the -m flag are using it for megabytes display. But the inconsistency for -g makes it seem a bad idea to support. (-k is the only size formatting which is an _actual_ standard).
