As described by `astoeckel`, if feeding
```
echo -en "\e["`printf '99;%.0s' {0..15}`m | ./test
```

which is not a sever issue since the `num_params` element
behind the buffer gets reset afterwards. However, he

I understand that the original author might not want to include these changes because of that. But everybody
