Broken setlist with or (and) construct

[toxamin]

When given the following script:

local t = cond or {255, 255, 255, 255}
print(t[1])

Metaworm's luadec produces the following output:

local r0_0 = cond
if not r0_0 then
  r0_0 = {}
  local r1_0 = 255
  local r2_0 = 255
  local r3_0 = 255
  local r4_0 = 255
  -- setlist for #0 failed
end
print(r0_0[1])
