Both mksh R28 (to be released soon) and pdksh disable
braceexpand in posix mode (set -o posix), but older
mksh versions don't, so this diff is preferred, plus

I believe no one can invent an algorithm. One just happens to hit upon it
when God enlightens him. Or only God invents algorithms, we merely copy them.
If you don't believe in God, just consider God as Nature if you won't deny
existence.		-- Coywolf Qi Hunt
