Does anyone remember what MCL did? I recall that we did have a
solution, but I don't recall what it was.
Escape currently works as a preface key to indicate meta, right? It
did just now when I tried it, so I'll assume it works consistently.
How about if we just add a switch that controls the meaning of the
option key. We ship with the current mapping (option = meta), but we
allow people to turn that off, so the option key returns to its normal
Macintosh purpose, leaving escape as the way to indicate meta.
