Sorry, one line of Lua should be inserted right here for the case of a
single Set-Cookie response header:

            if type(cookies) ~= "table" then cookies = {cookies} end

that is, ngx.header.set_cookie will just return a single Lua string
instead of a Lua table if there's only one Set-Cookie header.
