Subject: [PATCH] Fix rewrite io.input inside io.lines.

```
do
	local t = os.tmpname()
	local f = io.open(t, 'w')
	f:write('test')
	f:close()

	local i = io.input()
	for l in io.lines(t) do end
	local n = io.input()
	assert(n == i, tostring(n).." ~= "..tostring(i))
	os.remove(t)
	print('+')
end
```
