Subject: [PATCH 1/3] Fixes https://github.com/HybridDog/nether-pack/issues/6

```
Use:
local tab = minetest.wrap_text(content, guide_size.fx, true)
Needs 3rd argument 'true' to ensure 'tab' is a table.
See https://github.com/minetest/minetest/blob/649eef9e4fe4ef6a59ca9f59c900c6e0900cfb3a/builtin/common/misc_helpers.lua#L311
```
