I think that we should make /s the official modifier in order to match
the disassembler modifier.

We should definitely keep /m for backwards compatibility, though I
don't have an issue with it's behaviour changing to match /s.  My
concern is more about trying to keep the flags consistent as much as
possible.  The change in flags would need a NEWS and manual update.

Thanks,
