Subject: [PATCH] EOZ (-1) not a space char. Fix bug with endless loop at not
 ended \z sequence.

```
local function lexerror (s, err)
  local st, msg = load('return ' .. s, '')
  if err ~= '<eof>' then err = err .. "'" end
  assert(not st and string.find(msg, "near .-" .. err))
end

lexerror("'alo \\z  \n\n", "<eof>")
```
