I've seen several scripts in the wild that used fold and/or fmt.

Here is a basic implementation of fold[0]. It does not support multibyte characters, though that would probably just require more switch cases. This is my first contribution, so please comment your thoughts/what I can improve.<br>
<br>
I was planning to write an "unfold" utility that basically did the opposite. Although I don't think it's in any standard, would it still be of any interest?<br>
