[coreutils] Enhancement idea: Could "-M" be made the new short option for "--si" in ls,du, and df

[Tom Trauth]

Since “-H” can no longer be used as the short option for “--si“ (except in df) due to the POSIX requirement that it be the short option for “--dereference-command-line”, could “-M” be used as its replacement?  Neither ls, du, nor df currently have an “-M” option (though ls and du have “-m”), so it is available in all three commands.  Additionally, SI is colloquially called the Metric system, so “-M” has some mnemonic value to it.  Any thoughts?
