Hi, Nick,

I am not sure what can be good about it. A space that separated subcmd
from the rest remains with the rest anyways and adding another will
double it:
local 0 `"foo "bar""'

. gettoken subcmd 0: 0

. di `"[`0']"'
[ "bar"]

. local 0 `subcmd' `0'

. di `"[`0']"'
[foo  "bar"]

Regards, Sergiy
