I don't think it's worth the complexity. I don't usually look at
References, and the default mhl.headers doesn't cause it to be displayed.
It's not the stuff in mhl.headers that I care about, it's what appears
in the draft reply message; that's where this would show up.
Like I said, I'm not sure it's worth it; that's why I'm sounding it
out.
With regards to what Ralph said ... AFAICT, space-splitting tokens in
a References: header should be fine.
