I doubt that would be sufficent or appropriate. If some caller _WANTS_ to
add a SP, shouldn't we be devising a way to tell zsh to add it without
quoting, instead of silently stripping?

Ok, use of "-o nospace" in Zsh is what I missed. I thought the issue was
about the nospace emulation.
So does that mean we would be forcing zsh users to add SP themselves? I
wonder if we can do better than that.
